I went with the DC Sports TCS (and header)...
I really love the sound I get from the TCS, very deep and authoritive, I never was a bumble-bee exhaust kinda guy. I have had one of the welds break twice in the same place but DC has made it right immediately both times at zero cost to me. The look of the TCS is awesome, I get many questions about the design (especially while getting gas).
Overall I am very pleased with the TCS. There are sound clips available on one of my sites...
