I purchased the down pipe, cat, and y pipe from a friend, then added the racing beat mufflers. I went from three bad cats, to one new cat. It was virtually a straight through exhaust. It was a bit to loud for my taste. Sounded good but loud all the time. So I went to my local muffler shop and they custom made a down pipe and added a resonator. Now it sounds great. It has a very smooth tuned sound. Very quiet at cruising speeds on level ground, and awesome when on the throttle. Heads are spinning when I go buy now. I will never have it any other way.

 

Im surprized that one cat didn't do it for you so im guessing your n/a? A resonator will usually do the job though. Congrats on the setup. How did the power band feel after the exhaust. Im just curiouse because it does a lot for the turboII but im not sure how much you get n/a.

 

I haven't noticed a difference at all. It just sounds sooo much better.
