I was going to get the Descendant exhaust, but have decided to open myself up to other options. Which one do you folks suggest I go with?

GReddy...among the priciest but it sounds beautiful. 3" too

For turbo, I'm with him. You'll benefit some from the larger pipe diameter with that application. If you're already planning on dropping the change on the turbo, might as well finish it with a large exhaust.

Without question the PTuning exhaust is my favorite. 3" SS from the S pipe back if you dont have their turbo kit. For turbo there is nothing better.

It's not quite a 3" as it's a 2.75" inch system (70mm).

Here's more info on spec and sound clip (http://www.shopgreddy.com/exhaust-headers-dp-en/rs-racing-sports-exhaust/scion-tc2-rs-exhaust.html)

This is the same system used on our Time Attack TC2 (http://greddy-usa.blogspot.com/2011/06/greddy-11-tc-rd3-video-recap-rd4-this.html) making 360+ hp.

DSport magazine also did a product review which you can see the results here (http://www.scionlife.com/forums/showthread.php?t=209954)

I wasn't aware ptuning make an exhaust, but I know they sell other manufacturers' exhaust kits, though. Which one did you get?
