Well I put on a duel in duel out super 40 flow, sounds really good, light drone while driving, good aggressive sound during hard acceleration, and a good smooth idle, not to loud and not to quiet...oh and I dumped the pipes over the rear end...

On the other hand, what are your thoughts on the high flow cat systems offered by flowmaster? Is it hard to relocate the o2 sensor. Does it make a difference in mileage and sound?
