Ok so I have my SLP LMs on the GT with CAI and Bama race tune. I want a little deaper tone and what ever performance benefits I can get but do not want the car to be so loud my neighbors hate me. I am looking at headers or MAC Pro Chambers. But which ones should I get, the off-road or the regular? Any buddy have any advice?

 

if you change out the mid-pipe, please use high-flow cats. they're still loud as hell with the SLPs but won't sound like total garbage like the catless setup will.

 

My catless setup doesn't sound like garbage.

 

subjective. every setup i tried without cats had the same raw sound that lacked a true tone. i was just noise that shot out the back, nothing smooth about it.. not like catless setups on the older stangs

 

sailing220 I am looking at the same set up that you have. Whats the best mod? The headers or the Pro Chamber? How much louder?
