Getting Ready to Re-do My Exhaust, Opinions?

Yea i'm afraid the race will be annoyingly loud. On a scale from 1-10 how much louder would you say the bassanis are than the magnaflows?



I just want something that sounds good, maybe unique, and louder than magnaflows

Yup, sounds like bassani is what you need.

For volume, if stock is 0, mags are 3, bassani's would be like a 5, flows with resonators would be a 7.5 and flows without resonators would be a 9.5, straight pipes 10.

Bassani's are a little louder than magsnaflows, sounds different and its a nice different. I dont think you will be dissapointed with the rectangular bassani mufflers, but the only way you'll know if the race would suit you better would be to buy both, try one first, you dont like it, sell them and buy the other pair . I've had stock, borla, magnaflows, flowmasters with and without resonators, and bassanis so I can say out of those bassani's hands down for me, not from youtube videos but from experience

I think it's about time for me to chime in on this. If there are noticable HP increases with 2.5" pipes, then that is going in the right direction. I have owned 3 MKIII Supras all built with the exaust diameter in mind do to increase intake and exhaust flow to to bore, stroke, larger turbo, etc. As stated above, the bigger the pipe the lower the exaust velocity and the cooler the exhaust will get, which in turn will make it more dense and slow down, UNLESS you have the motor built producing more exhaust output, then a larger diameter pipe is needed. I've seen as high as 4.5" pipes on Supras producing over 1000hp. The smaller the pipe will give you higher velocity, but choke you out at higher RPMs causing unneeded backpressure. The myth of a car needing backpressure to run is completely absurd. And whoever says exhaust valve burning is caused by no back pressure has no idea what they are talking about. That happens because, either the ECU can't compensate for the added fuel needed from increased intake and exhaust flow, and drops below stoich, say below 13 or 12:1, or you have a carbbed vehicle that does not have the jets to push ebnough CFMs. You have to marry flow capacity with velocity. If you see HP increases then it's great and the right decision has been made. Optimal would be to wrap your entire system to keep the exhaust as hot as possible, thus increasing velocity. Mlara I'd say go for it. If you see increases in power through most of all the powerband then you've hit the nail on the head. I have already bought Cherry Bomb extremes. They flow 500cfm and I will be going 2.5" myself. If I see a loss low end, I'll wrap my entire exhaust system.

Ahhh, thank you for the clarification. Didn't realize the heating of the exhaust increased airflow through it. That definitely was the missing element in this conversation
 
It's not that complex once you understand that need to match capacity with velocity. The hotter the exhaust is the better it will flow. A garden hose is a good analogy, but if you increase water flow you will have to end up taking your finger off the hose to allow more flow so you won't hurt your finger. Thus my point. A better analogy would be lava. The hotter it is, the better it flows. The bigger the volcano, the more lava it will spew, and so on and so forth.
 
I mean, that makes sense. Considering it was built to run hot, it makes sense that as it gets hot, and of course expands, its going to reach its peak efficiency. So of course finding the balance is the key

Thanks for the help Alex. I've decided to definitely go with the bassanis. Now just to decide which.

I emailed, a dealer of bassanis to see what the difference between them is, as far as tone and volume go. That should help me decide. As matter of fact i should contact bassani themselves...duh

If i can get the same tone out of the race bassanis, just louder ill definitely go with those. If tone is affected/different then ill just play it safe and go with the ones you have.
 
I will give my .02 from personal experience. For exhaust in the sizes we are talking about will not make all that much difference, especially if not mandrel
bent because 2 1/2 will be down to 2 1/4 on the bends if custom bent exhaust. The larger diamiter tubing will move the power band a little, if someone said they were going to use dual 3 1/2 in our cars that would not do well.
Now from my own experience with my 88LSC I ran full length headers and dual 3" on the stock motor with 4:10's. Car ran 14.6 in the 1/4, most with stock motor and exhaust/gears would run 14.7-14.8, granted diff. cars and drivers may make a diff. but I deffinetly did not loose any power with the
larger exhaust, if may have just moved to a diff. rpm range.
 
Just got off the phone with Bassani...

the race mufflers will be much louder and raspier, and could even get backfire lol

I guess ill go with the bx series.
 
I too would like to upgrade my exhaust system but currently trying to find a sound I like, IMO the bassani's are too raspy for me. What muffler do you have on your car now Mlara, I kinda like the way that sounds.
 
+1 race mufflers...or you could just do what i did and get electric exhaust cutouts and its loud as hell when you want it to be and quiet as stock with the flip of a switch
 
Just an update...

Had some issues placing my order for bassanis, but i should have them (and in my car) by the end of next week, hopefully.

I sourced a magnaflow x-pipe from the Jag forums with very little use and looks to be in good shape for $25!!! :eek:

oh and i'm going with the universal bassanis. If they're not loud enough for my taste ill look into going with the race mufflers.
 
You're gonna love the Bassanis, dude. And if you don't, I'll come find you and smack some sense into you. :D

I was looking for them for the 550, but there's no videos out there of a car like mine with them. Didn't wanna bite the bullet on them and get something that drones it's balls off. :/
 
Nice find on the x-pipe.

What issues did you have while ordering?
 
issues with my debit card. Wells decided to issue me a new one because apparently my old one was in risk of being compromised. Should be getting the new one early this week then i can place my order.
 
Bassani Mufflers!

Just placed my order. Can't wait.

By the way they are on sale. Part #4820. They are $89 each on the bassani webstore instead of $212(ebay) or $115 (autoaccessories). 4820 should be the configuration you need (center in, offset out) unless you changed your pipe configuration when you did your last exhaust set up.

Question about tips:

Trying to save wherever i can, so do you guys think i can get away with using these:
http://www.ebay.com/itm/MagnaFlow-P...ies&hash=item4d005c1062&vxp=mtr#ht_1454wt_952

versus these:
http://www.ebay.com/itm/MagnaFlow-P...ies&hash=item5ae627f368&vxp=mtr#ht_1454wt_952

or do you guys think they'll be too short?
 
If you are going to have an exhaust shop do it too short is never a problem, they can add the 3 inches if needed.

Nice find on the Bassani's

Newb question, sorry. So after buying the Mufflers, Xpipe, tips and such, you have your shop do all of the actual fab and bending to make the rest of the piping yes? And depending on the shop they can do mandrel, for probably more money I would imagine right?
 
Yes shops do this kind of stuff all the time. You can simply cut off old stuff and patch in new stuff or you can get a full complete stainless steel polished system.

I dont look at my exhaust enough to care. Its not a show car...just want it to sound good and not leak.
 
But the tip itself is too short to look good on the LS, you will be able to see the tip end from behind as apposed to the 7.5'', the narrower diameter where the tip ends is hidden behind the bumper because its longer.

Those 2 are different tips if you hadn't noticed. The first are flat and the second are angled 15 degrees, angled looked better to me, but its up to you.
 
If the guy doing the exhaust just extended the other end between muffler and the tip they would extend paste the bumper and it would not be a problem. Do you have any pictures of the way it was that burned your bumper, I never saw that before unless was really behind the bumper, and if so should have not been left that way.

Way too short. I had 4" tips and melted part of my bumper remember?

I think my current tips are 7.5" long and they barely push out past my bumper but just enough.
