I had my mind leaning towards a Magnaflow but then the muffler man roped me into putting Flowmaster 40 with a pipe out each side canted behind the tires each fitted with a polished stainless steel double rolled edge 20"x3" tip.

It is aggressive but I would like the resonance to be a bit less but what the hell I just turn up the XM comedy channel on the radio and drowned it all out laughing--lol

Zoomers claims almost zero resonance on their setups and they sound pretty good in the clips on their site. Plus I heard they have a decent sell on right now.
