So I'm shopping around for an exhaust. I got it narrowed down to 4. Zoomers, loudmouth, pypes violators, and solo. My question... Is 3in too big for an RT? I know a bunch of ppl are running with zoomers so I'm sure it's not really an issue but what issues can come up with the 3inch. I don't really plan on modding the engine much. Possibly a CAI and a tuner but that will be much down the road even if I decide to do it. Am I better sticking with the 2.5 inch pipes. I also understand that where the catback connects its still going to be 2.5in then 3in back from there but won't I still have back pressure issues especially with the loudmouths considering they are basically straight pipes. I'm sure this has come up in several threads but somehow could find it. You you know of one feel free to direct me there. Thanks in advance.
