So I'm new to this whole forum thing and j know this thread has been dead for a long time but I figured I'd share what I came up with as a solution to the aftermarket exhaust. I recently built a cat back system that bolts right up to the secondary cat, removes the resonator, has an aftermarket chambered muffler to avoid losing too much back pressure, and I increased the pipe size from 1.5" to 1.75" only because it was easier to come by. It utilizes all factory hangers, has flanges in the factory locations(at the cat and above the rear axle), and is basically a direct bolt in with the exception of the tip(I'll get to that in a minute). I used a thrush welded muffler with a 2.25" inlet and outlet and it does not sound raspy in the slightest bit. It's actually pretty deep for the size motor. The tip also exits through the rear bumper like it does in the Chevy Beats that they sell over seas. It looks better in my opinion and it also helps with the interior resonation because the sound waves aren't getting trapped under the car. Let me know what you guys think. For the record, I know the welds aren't the best looking considering I used a flux cored welder and the fact that I'm an electrician and not a welder by trade. But there are not leaks so that's a plus.
