I have it. It is one of the best Cat-Back's out there.
The main pipes are 3.5". And it does produce the power.

I am interested in this system for my '89, and asked TPIS lots of questions. Do you still have your catalytic converters in place, and what was the difference in sound with the TPIS? Do you have pictures of it on the car?

Thanks,

I got the whole system from them, headers, 3 inch cat and the cat back. Awsome but may be a little loud for some. Right now I awaiting my new engine(383) and will listen again shortly.

I have the cat balk and their headers on my L-98. My only beef is that the tips seem to stick out too far. I wacked them by ~1.25". Pic in signiture. The system is loud, but may be due to the engine.

I have TPIS headers, gutted cat, and the TPIS cat-back on my '86 and love it. I might need to repaint it but other than that it sounds great and definitely flows, love the tips.
