Well I put my testpipe on yesterday. Damn is it loud now, and the bad thing is that it sounds like a honda now.:( I bought it from www.testpipe.com for 30 bucks. I guess I'll live with the sound until I get a highflow cat.

What kind of sound does it make , a high pitch civic like sound?
Do you completely lose the deep tone and low end torque? Did you get a CEL? What did you do with the O2 sensor? Since this is the question game hehe... What kind of projectors are thos in your sig pic?

put in a nice big resonator.. like a cherry bomb.. that'll get rid of the high pitched noise and make it nice and deeper.

Yes it is a civic like sound... The O2 sensor isn't conected to the cat in any way. I wouldn't know about the CEL because I took the bulb out a long time ago. Freekin anoying. I bought the projectors from www.autodynamic.com don't know which company made them, doesn't say. I didn't notice any loss in low end power. Not as bad as when I put my Tanabe catback on.
