Finally got the new 40 series cat back system 2.5" piping. Sounds great! At least added 10hp the power band moved from 2500 to 3000 and cruising at 2000 just rumbles man its great. only 185 bucks for a new cat back system can't beat that!!

 

Let's hear a sound clip.

 

Do they make one for the 50 series? And in 2 1/4" piping?

 

well yes ask the your muffler guy to fabricate it for you. Thats what they did from mine it wasn't a kit from flowmaster it was fabricated 2.5" piping with a 40 Series.

 

I've always heard you'd lose power with 2.5". You didn't experience that? Maybe the fact that it's crush bent adds enough backpressure... Did you feel like you lost any low end torque?

 

no not at all it feels even like it has a bit more. I think once you get up to 3" you start to see a difference, but no i haven't noticed any difference in low end torque.
