So after picking my unmolested 09’ GT up a couple weeks ago, I’ve already started to tear into her. I took out the midmuffler and replaced with an X-pipe, kept the stock resonators and added two single chamber mufflers at the rear with some Trapezoid tips I tracked down online after searching forever to find a set that fit the bumper jusssttttt right. And I LOVE IT!!! I’m pleasantly surprised at how it sounds with the single chambers, I thought it might be a bit louder but it’s perfect. I know once my long tubes and cam get here that it’s gonna change but still. I had the 3.5” quads on my black car but I wanted to do something different with this one. I also went with the Spectre Intake this time around.
