gtp exhaust size.

You need a new cat man it's probably clogged, and I have magna flows on my car and they sound really good I'll post a vid of mine I just got mine done also and I don't have a resonator but I don't drive mine that often if it's your daily driver I would suggest getting a resonator.
 


Any 3800 should have a resonator...DD or not. It makes or breaks the exhaust note...even though it isn't great anyways.

Have you experienced a good exhaust note? SLP's only sound good with a BIG resonator...that and the fact they ARE raspy...since they are designed for a V8 car in the long run. 2 good friends of mine runs SLP catbacks on their GP's...and I just don't like them...call it whatever you want...but they belong on a LSx car with a loudmouth 1.
 
I am gonna agree v8 sound amazing and a v6 will never come close to it except the infinity g35 but tellme what u think when I post a vid up
 
Probably because it sounds bad without the resonator and it the camera is actually letting you know what it sounds like.
 




Went out and did some measuring for anyone who is as confused as I was. The stock muffler is 14" long by 11.5" wide and 8" thick with offset 2" inlet and center 2.25" outlet. Also the stock resonator is 29" long.
