Great gain in performance, but did add a little more noise from exhaust.

Item was shipped fast. After opening the box, the downpipe looked beautiful. Nice welds all around and was even supplied w/gaskets (however I would have liked the gasket that goes from the exhaust manifold to the downpipe to have "ears." This would have helped w/installation). Nevertheless, installation was quick and simple. 4 bolts along w/replacing the O2 sensor. What I love most about this product is that it eliminated the "U Bend" that the stock downpipe had. Do not regret spending $500.

Excellent sound without being obnoxious. I did have the LH side that was 2" lowere than the RH side. PYPES sent me out a replacement a few days later. Overall good experience & can't be beat for the money. Look excellent.
