    Default New Exhaust and Intake Installed

    I just installed a Gibson Cat Back Dual exhaust and Volant Air Intake. It sounds great, too early to tell if it made any improvements. Ill be taking it to the track tomorrow to see if it does anything. I have to get pics in a few hours, the camera is in my wifes purse!

    It will be interesting to see how much difference that makes to your 1/4 mile times.

    X2 on the interesting part, especially since I'm also running a Gibson cat back and Volant intake!

    That's always nice when you can knock two birds out with one stone, can't wait to see some pictures of the new mods. I would bet that you will see 15-20hp total improvement, and probably 2 tenths off the quarter mile. Great choices as far as products go, do it right the first time or don't do it at all.......
