It must have been to late for me, wasn't thinking. I realized today, it's gonna be a single exhaust, not duals. Since this is the case, are u reccomending 3" single out, no cats no res? I actually would love the look of only a single pipe coming out the back. I'll have one of the exhaust cutouts out back covered up and painted! I think that would look *****en. I actually rather have a single, I love the look.
