any input ive heard it sounds like a v8 or is it just a bad idea

It will sound good, but probably illegal. I suggest some Cherry Bomb mufflers and straight pipes.

Bad idea. IMO its a waste of time to try and make a six sound good like an eight, just go buy one of these:

IMO straight pipes sound all thin, no good tone because thier nothing to resosnate the sound.

I have a flowmater 80 series w/2.5" pipe and its leagal and loud :D

Plus you need some back pressure or youre going to ruin the motor.
