Hey everyone, still a newbie here. I finally got my cat back exhaust done. I replaced the crappy factory Y pep with a new one from Flowmaster and also installed their 50 series HD muffler. I removed the factory resonator as well, it sounds really Awesome!!!! I already have the Diablo in tune tuner and will now get that going. More to come on that later. I haven't had the opportunity to upload photos, but will soon. Thank you all for contributing to such a great site. We'll chat soon.
