i actually LOL'd at that one :P

will it still sound good and give me a little more power if i just get the conversion kit flowmaster dual exhuast? or is a big difference between true dual and the conversion?

You can use any mid pipe and catback for a gt. Itll be a noticeable difference...Itll basically bolt right up to your manifolds

Pretty big difference in sound, only minimal difference in performance.

Is like going from a 4stroke dirtbike to a 2stroke in sound :P

so would the conversion be bad? or get the whole thing? and any gt's do work for v6?
