This is what I've wondered about ''other'' HFC's and test pipes. That the O2 sensor bung is not long enough to completly solve this issue.

See on my GTM TP the bung is longer and cuts back away from the exhaust flow.

By the way great looking car and exhaust. Also great vid.

thanks for the compliments... those GTM pipes look nice as well! see some of you all next weekend!

Yea. Can't wait.

Im attempting to bring life back to this thread. I'm in the market for some test pipes, I dont wanna spend ART pipe money, although Id love to as they look amazing. Looking more around the 2-3 hundred range. Contemplating CNT resonated pipes. I also see the Top Speed pipes are a great deal and they even have the 90° 02 bung. I just worry they are of poop quality. So basically what are you guys running???? What pipes arent giving you tons of rasp??? Will resonated pipes really sound that much better??? Id especially like to hear from CNT, TOP SPEED, INVIDIA & AAM owners. Thanks guys, please comment.
