I was wondering is any of the SLP Catbacks 3 inch? if not does anyone know any catbacks that are 3 inch? I have 02gt

 

You will lose hp if you put on 3in due to lack of back pressure, you only need 2.5 and get a bigger tailpipe if you like.

 

what do u mean by tailpipe? muffler?

 

looks like I need to make an instructional video...

 

The slps are 2.5in but the tailpipes are 3.5 in. What I was trying to point out is if you just want bigger tailpipes you could always weld on bigger tailpipes on any catback but you should stick with 2.5in max unless you have a turbo and dont need the backpressure but NA cars need some backpressure if your pipes are too wide you will lose hp.

 

As long as you don't include that damn song...It's stuck in my head.
