I have the Magnaflow 16633 cat-back.......absolutely love it!

Me and MI1XFIRE were the only 2 (I'm pretty sure) at the Woodward cruise with them on......everyone else loved the sound, even the SRT guys.

The Magnaflow is a little loud at first, but it mellows out with time, or in my case....a few runs down the dragstrip! When I first put it on, I thought "damn....maybe I want to switch back to stock right now"...glad I gave it some time. Now I'll freeze my a** off with the windows down just to hear it play it's music!
