imo bassani w/an o/r x-pipe is the best ive heard but bassani is a little pricey but i have magnaflows and an o/r x-pipe i used to have an h-pipe w/flowmasters and it was too loud and droned way too much and the o/r h-pipe w/the magnaflows made alot of popping noise and sounded like crap below 3k rpms so i swapped to and o/r x-pipe and it is just right its not too loud but you can definently hear it its got a nice deep tone to it when cruising and when you get on it it absolutely screams and its a made very well i suggest it my dad ordered for off a name a price site might have been parts shopper i dunno and got it brand new for $300 ill ask him where he got it when he gets home
