Thanks, no test pipe right now b/c I don't like the smell you get with those, there's a good amount of drone but it's weird, it sounds good b/c it's just a real low rumbling kind of sound.

It feels like the car picked up power, I dunno but it seems to me like the dyno was done weird -- first he basically started it up and immediately did a pull (after the exhaust was on), and got yelled at by another guy in the shop. Then they let it sit there and idle for 3-4 minutes on the dyno before the second pull, the fans came on about 30 sec. before the pull b/c the engine was so hot. Also, there was something weird w/ the rear dyno straps rattling against the exhaust, so they had to move the car back on they dyno and do the straps a weird way, I dunno but that might've affected the dyno too.

 

Did you have the cat in with the stock exhaust on the first dyno?

 

Yes I did, it was still in when I switched exhausts too, why?
