In the quest for H.P. Has anyone thought of removing the exhaust system & rigging inexpensive tubing & glasspack or similar type muffler,s . We know helping the powerplant breathe increases H.P. Just a curiosity question.

Loud exhaust on a lincoln?

What?

Posted by: NJ95MARK8

modular engines need back pressure to run properly not only rigging a cheap exhaust hurt your performance it will also hurt your engine. if you want to be cheap get a honda and ghetto rig a coffee can exhaust on it or somthing. you drive a lincoln mods and accessories are going to be expensive. you buy the name you pay to be in the game. save up plan and do it right.
i suggest a lms tripple x cross over to a lms cat back exhaust. order it all from geno then have a local shop fab it on. i have stock exhaust on flowmasters as we speak. i talked to geno and in about a month or so i will be doing my exhaust.
lincoln= not cheap

Id remove the 3rd cat and due a 2 in 2 out magnaflow, When I do my exhaust im gonna due a 2 in 2 out magnaflow with all cats removed o2 simulators in there place.

Third Cat? On an LS?

Posted by: ghostBuster

dude you have no idea what you are talking about there are only 2 cats on a ls

Posted by: Mac98SHO

Ouch, that honda thing was below the belt... he just ask a question, be nice

I would sub the glass packs with flowmasters, see how it sounds.... you can use either 2 or 3 chambered.

Glass packs actually create more back pressure, according to what I was told by an experienced exhaust specialist. Me I never like how they sounded.

Good luck, keep us posted.

Posted by: ghostBuster

dude there are things that you can do to get a better sound then putting glasspacks on your ls like a 2 1/2 in or a 3in with supper 40s from flowmaster

Flowmaster mufflers are horrible, if you look at the flow bench numbers you'll notice that flowmasters will, without a doubt rank at the bottom. And yes, you could do your own exhaust, your best bet are to get some car sound cats to replace the stock ones. However, if not thats ok.

I highly recommend getting a magnaflow system for your vehicle. It is easily the cheapest highest quality exhaust kit your going to get for about $500. The flow numbers on this are great and should net you a realistic 5-10hp, it has a nice tone to it you can here but its not that loud. I think it might be a good compromise.

Also, their are PLENTY of people who work on their equally expensive corvettes so don't be discouraged into delving into this project yourself. If you've got the tools and time there is no reason not to. If not, an exhaust shop will do it for cheap.

If you decide to do it make sure you get the right one for your year of vehicle.

On the '03+ LS there is a third cat that replaces the x-pipe on the '00-'02

I don't belive so. It is listed as a resonator in the parts book, not a third cat.

An SCT tune and cold air intake are the only horsepower mods actually produced for the 03+ LS's that I am currently aware of. You can mod the exhaust for sound but probably wont get much in the way of additional power.

The SCT Xcal2 or Xcal2 SF will run you anywhere from $300-$395 depending on the dealer. If you have hookups within the SCT community you can get them for much cheaper.

There are two CAI's made for the 03+ LS's. KKM produces one through which Gray Ghost (LsKoncepts) sells through here; and I also make one for the V8 that is a little more complete but also more expensive.

Other than that there isn't anything else specifically made for the 03+ LS. The Lincoln LS will not gain any more popularity with the aftermarket community than it already has. Being that the LS has been cancelled there is no real reason for a lot of people to jump on a dying aftermarket now. The tough luck is that the LS wasnt really recognized by the aftermarket all that much and it is only going to get worse. That is why some of the people with good fabbing skills from this board end up taking things into their own hands and creating their own aftermarket mods. I had to do the same thing with my 03 Explorer because no one produced a high horsepower capable supercharger for them. I guess with all my blabbing what I am trying to say is that sometimes a person has to take the aftermarket into their own hands, provided that they know what they're doing...

Rocket, do you have a web site or pics of your CAI? I have the KKM on mine and need the "cold air box".

He's not really offering a box but rather an extended tube for a "true" cold air intake. Basically the filter will NOT be in the engine bay.

My home made insulated box works well, but I would still like to have a more "finished" insulating box for my system someday.

Yep. Ken is right. As for now the one I already have developed is in the engine bay. Once it gets a touch warmer here and I can work outside in comfort again I will tackle the fitment issues with the fenderwell CAI. As of now I only have pictures of the engine bay CAI. Just let me know if you still want them and I can email some to you.

Is that supposed to be one of those things you put on your windshield on a hot day?

You talking about GWL's heatshield thingy? Now that ya mention it I do see a resemblance in material.

I Would Go With Gutting Out Cats And Pre Mufflers And Adding 2 Flowmasters, I Have A 95 Lsc Thats What I Did It Sounds Great!!! My Buddy Had A Standard 95 Mark And He Had To Add The X-pipe That Comes Stock With The Lsc's And He Has Magna Flow....sounds Gay, Not A Very Noticable Sound What So Ever, But Some People Just Want A Very Quite Exuast With Some Tone If Your That Kind Of Person Go With The Magna Flows, If U Want A More Aggressive Tone However, I Would Do What Exactly As I Listed That I Did On Mine. Good Luck With Whatever U Choose!

Off topic. There are such things called periods. They work great for punctuation instead of substituting comma's all the time.

Just giving ya a hard time man.

OK. im not an expert but i have completely removed all the exaust and emissions components(cats) and nothing but my check engine light has come on for obvios reasons. as far as preformance goes at least by the seat of my pants lower rpm's and takeoff a bit slower but i feel a huge difference in top end high rpm acceleration, and its prob the best sounding and loudest exaust ive yet to hear on an ls. you think its ghetto fine, but i paid 15K for mine and you can get one for 10k now used. so im gonna keep riggin it and beatin the hell out of it till it expoldes then get another one. To hell with payin 800+ for an exhaust
2000 LS V8
gutted
dropped 2in (cut springs)
limo tints
intake (rigged)

nope - if you go too big with the exhaust (like cut-outs or 4" piping) you will end up moving the torque curve up the rpm scale because you have lost soo much backpressure.

so you need some backpressure to have the torgue down in the lower rpms for a good launch - but too much will build at the higher rpms and hurt the performance there.

so like anything else - it's a trade.

I agree! I do my own exhaust, and i did mandrel bent 2.5 inch with a home made scavenger pipe and the 4inX9in mangnaflows. I LOST low end but gained a

load of mid and top ranger performance.

Posted by: LSVIPDEMON

Dude dont get a magnaflow they sound like crap have someone get you the pipes and get some other mufflers. My magnaflow also cracked at some welds with only about 10k miles. I think Im gunna try the flowmaster hush power 2.

Posted by: NateRW21

I know it was a while ago, but i saw the post where someone was making reference to our 3.9L as a "mod motor". Well, I have to make the correction; the 3.9L is not in the modular family, it has entirely it's own architecture. The 3.9L is BASED off the 4.0L Jag engine, however they share almost no commonality what so ever.

Mod motor V8's are limited to the 4.6, 5.4 and the VERY RARE and expensive 5.0 "cammer" which is a FMS parts crate engine. Then there is the 6.8L V10. That's it as far as the mod motor family goes.

And on a side note... a lack of back pressure will not damage your engine in and of itself. As was stated, back pressure builds lower end torque. Inversely, lack of back pressure creates high RPM torque. You can have one, but not both. If you pay attention, most racing engines run very very simple, virtually back-pressure free exhausts; these engines also live a life of constant high RPMs and will only see numbers below 3000-4000RPM when they idle.

Exactly, paid 15k for my 2000 ls sport, and you know what the dealership paid 32k in warranty covered repairs ( 50 thousand mile curse) and I see em going for a lot less than 10k even with the premium 75k powertrain warranty like I have. Every 19 year old gangsta now owns one anyways for that reason as well, so ghetto realy should have no deffinition here considering there is not alot of aftermarket selections for this car. So then again, is it realy ghetto cause you made it for under 500 bucks and didnt pay over a grand for elegance that lasted 10 thousand miles like mine. I wish I would have just got the pipes from some barn yard machine shop and used my own mufflers. It sure isnt ghetto to all the hotroders that ripped the cats off and sent a straight pipe out the side as soon as they get the car cause they like it loud. Dude configure the pipes yourself, thats your perogative and I realy think it kinda sounds more like blowing up rice with an american car.

Sorry this was supposed to follow loudisgood666 post just above a few. OOOOOPS.

What do you think about those universal filters with the metal shield around the cone and not shaped like a box

Posted by: 02lincolnlsv8

Why cant you just get rid of your mufflers completely on an LS? Or can you? Wouldnt running no mufflers at all be louder and more powerful than running mufflers? What are the positives and negatives to doing this? Any responses are greatly appreciated

If you did this you could keep all your stock tubing to. What are the positives and negatives to doing this? Any responses are greatly appreciated

How can it be march and no answer to that?
I actually did try that.I took my 02 off the hoist after cutting the muffs off and took it for a ride...As soon as we started it , it sounded like an old 5L...Quite nice actually. However , hard hitting out on the road , and it was wayyyyyyyy too loud for a luxury sport , and did crackle/pop on throttle lift.
Great at an idle tho!

Posted by: Quik LS

What answer are you looking for?

Posted by: B_Kuz

5 months with no further data on running muflerless... hmmm... has anyone else tried? I'm more looking for dyno results, not just seat of the pants... also, what would I need to have torrie change with my xCal profiles to take advantage of the lower backpresure? Thanx in advance for any solid info...

Posted by: loud00ls

ive actually been running straight 2 1/2 inch pipe to a magnaflow x-pipe and straight back with no cats or mufflers for about 6 or 7 months now... and i get compliments all the time about how good it sounds.. but i also get people who complain about how its to loud.... but who cares i love it..... as for backpressure, i have felt no loss in torque but a huge gain in high rpm horsepower ..but when u loose backpressure its allways a good idea to open up the intake side (intake, ported TB & Upper Intake Plenum) .....and to add a bit more fuel to keep from runing to lean.. .i have also had a custom tune made by torrie which does help alot.... but before the tune, it did run great without the mufflers and cats for a about 2 months. i hope i helped

Posted by: dubLS00

i just recently removed the back half of my exhaust running no resonators or mufflers and it was too loud for me. i did feel a difference in the high rpms tho but cops are too quick to pull over anyone in my area with an exhaust that loud. i only kept it like that for that night.

Posted by: tjboston5676

hi i have a 1992 lincoln town car with the modular 4.6l and im trying to make it fast but i used to have the exhaust detached from the downpipe back so about the equivalent of long tube headers with a little extra length but it sounded freakin awesome and a slight increase in performance but recently i gutted the cats and wit the exhaust how i used to hve it i lost a tone of low end power from the lack of back pressure wich was provided by my cats before and plus it leaves that big chamber where the gases start to rotate in and causes less power so now i put pieces of metal in between where the down pipe and mid pipe connect and then tightened the bolts on to it to leave about a 1/4" gap doesnt sound very good because u can here the air ruching around the corners but did see improved power and plan on eventually putting 2.5" mustang manifolds with 2.5" x-pipe and maybe hook the rest of the exhuast all the way up and btw i have 12" glasspacks so what gases to keep flowing trough go through those and when its all bolted up it sounds nice but too much of a 4 cylinder sound and not loud enough for me but theres some info for u if u can replace ur catted downpipes with straight pipes and since its pot 96 use o2 eliminaters and u should see some power and if u want leave it open like i have mine or get some flowmast single chambers

Posted by: zachg2001

Dyno tuned no mufflers 3 inch 2 foot long SS tips been like that for 3 months loud at times but i have bridgestone potenza's on the car so im not relly going shooting for quite!! Old people say you arent supose to hear a luxary car all the car buffs Drule when they hear it, ive had a few cops and a state patrol compliment my exhaust.The first thing everyone needs to do is get a SCT and have the throttle open delay turned off and the shift firmness maxed.

Posted by: zachg2001

u can kinda hear my exhaust in this video its a long video but its good my car is alittle after 7 min into the video after the red sn95 stang does a burnout.

Just wanted to let yall know that I've put 12" glass packs on my '01 Ls and I know your probably think'n idiot but it actually has a nice tone though, I get compliments on it all the time people think its actually bigger than what it is most people think that it is a 4.6 out of a mustang, kinda sounds like one..that was the sound I was going for so it works for me, dont know if I lost any or gained any last time @ the strip I was a little slower but I did have a half a tank of gas, new tranny, and exhaust, not to make excuses.

Posted by: tjboston5676

i am now running straiht pipes sounds GREAT and its not too loud either im guessing the way the tailpipes are it cuts back on the sound but i like it

Posted by: Jayce 1971

About the original question, ls steve. Have you ever considered lake-pipes or cutouts? That would be exactly what you need. Loud when you want, quiet when you dont.

3 1/2" header back with magnaflows FTW!

Posted by: LEOV5

I have 05 LS v6. I had 2.5 with an x-pipe from the resonators back to 2 Magnaflows installed. These are 18" 4x9 and yes I lost some low-end, but at about 3000 rpm and above this really made a big difference. I have KKM CAI installed with my own engine block-off installed. The exhaust makes a nice euro sound when I start her up and nice tone as I accelerate. I am very pleased with the outcome and all of my car buff friends like the way it sounds also.
