Ok, my current exhaust setup is gutted manifolds, optimized Y, and Trubendz with magnaflow muffler. Now, I was on the trubendz site again and noticed they have test pipes for Cougars now, and was wondering if they would fit. Also, would this be beneficial, because the one I am looking at retains the cat, and I was under the impression that a test pipe eliminated the cat altogether. Also, I just recently installed the gutted manifolds, and do not have MIL eliminators installed yet. Will the ones on the site work?
