Thread: 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.

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

Ok so i took a video of my car exhaust and sound quality of my camara sucks so it does my car no justice lol sorry guy.

Probably because it sounds bad without the resonator and it the camera is actually letting you know what it sounds like.

That could be a possibility but i lov how my car sounds.
