what should i do

[jdetten]

i have a 2003 gt with a american thunder catback and was wondering about a mid pipe. i want a deep rumble with it and loud . i was wanting to know how loud a catted hpipe is verses stock or should i not worry about inspection and either find a place to do it or change it my self when inspection comesthen change it back and get a prochamber or what about a catted xpipe thanx jon

today i just got rid of my slp and got flows

 

[Firemanz]

Prochamber and flows are music to my ears, I'll leave it at that....

 

[stangman]

prochambers sound amazing i can't wait to get my new one installed

 

[Sleepy1]

Agreed, prochambers sound very deep and intimidating

 

[Bone Racing]

flows and prochamber made me happy

 

[jdetten]

so is having a prochamber worth taking it off and putting it back on for inspecton and how much louder is the prochamber than a catted hpipe

i can't say how much louder than a after-market catted H, cause none of the guys i know run cats but i like it quite a bit better than a off road H
