Magnaflow

If it's your LS, just do mufflers. you don't need to mess with custom pipes. You won't gain anything but a different sound. The gen 2 exhaust was actually well engineered for flow.

If it's your brother's LS, what generation/engine?

+1, you can get good sound out of stock pipes and good mufflers out of the second gens
 
Mufflers only won't gain squat but a cat back will. The Gen 2 catback is so similar to the Gen 1 I doubt there is much pwer difference. Gen 2s got better manifolds and I think that is where the small gain of power came from.

Stock exhaust on all LSes is 2"

The MagnaFlow system is 2.25" They advertise it wrong as a 2.5"

If you go custom most go 2.5" as the crush bends narrow down some.


I'd tell you to search but there is alot of wrong info regarding exhaust on here.
 
OK, maybe I worded it wrong. You won't gain the performance necessary to justify spending 700 bucks on a cat back kit on a gen 2. Which I don't believe they make anyways.

On my gen 1 V8, I did 2.25" from the resonators back, since that part was actually smaller that the rest of the piping. Or so the shop said. The guy had already started before I got there in the morning, so I didn't get the chance to demand 2.5" pipe instead of 2.25.

It's a 2005 ultimate V8 .

1-2hp per $100 is normal for most cars. For some thats fine others want more bang for the buck...not really easy to do with this car.

The shop you used was kinda correct. Its the bends after the resonators and before the muffler that narrow the diameter of the stock pipe down. The pipe itself is technically the same size as before the resonators to the cat-back connection. Those bends are likely the most restrictive so you did improve it a little.


I'm happy with the MagnaFlow cat-back, its mandrel bend so no crush bends. And I happy with the power it gives over stock, even if just a little.
 
I'd love to drive a gen 1 with the magnaflow cat back kit to see the difference.

10-12hp is hard to feel.

The 40ish I've added some would probably expect to feel stronger.

I wasn't trying to offend. In fact, I was thinking that the difference would probably only be seen on the dyno and on the track. For someone who doesn't take their car to the track, maybe 300 on mufflers and custom pipes would be a better option.

Oh, and just replacing mufflers and the pipes from resonators back gave me just the tone I was looking for, albeit a hair on the quiet side. Damn Lincolns and their sound deadening :rolleyes:
 
roll down your windows :D

Maybe remove your rear mufflers, put in a magnaflow mid muffler dual in/dual out in place of the resonators. Nick88 knows a cop who thinks it's pretty loud.
 
Or if you are not interested in performance, and just noise, then get flowmasters. I don't know much about them though, so I can't guide you to which ones would sound good. I'd just search youtube for "Lincoln LS flowmasters" and see what comes up.
