what is better the 4in or the 5 in performance wise??? Thanks

theres really no performance difference because even a 5" system will have a 4" downpipe. It mostly just comes down yo your preference, and the cool factor.

Since there is no performance advantages Which one do you guys think sounds better??? 4 or 5in.???:c:

Igot a 4in down pipe into 5in into 6in stacks sounds awesome.:U:

5 inch dude :U:

Can't beat the sound of 5". Not sayin 4" sounds like crap but its amazing what an inch will do ;)

I've messed around with my exhaust, from running no muffler all the way to running it straight out the up-pipes. I think the longer and bigger the exhaust can be the deeper and more badass they sound.

Is the 5 in ungodley loud taking it easy on the peddle, or is it queit taking it easy?

I hear the 4in is quiet taking it easy and has alittle bark when you peg it. What do you guys think?

Depends on if you get a Kit with a Muffler

Mine's well within reason just fartin around town. However I'm not outside or behind it while I'm driving. Getting on it and you know your loud, regardless :rocking:

I did forget to mention mine is straight-piped. You can get a flow through muffler with both 4 and 5 inch. Exhaust is a guessing game sometimes.

I was and its loud! :U:
