Good question, don't get the downpipe unless your for sure getting a tune. After installing the downpipw my cel, cruise control, and traction light came on. Not sure about sound because i installed it all at once. For performace I have not got on it yet. April 27 is when I get my tuned at ams. I'll post up a thread after.
I also did the k&n intake, kinda loud, sounds like a big vacum leak.
I got my downpipe from VelocityFactor.net cause they had it in stock and free shipping. I did pay $595 though.
autopartswarehouse.com had it for $520 but it was on backorder from cobb.
