I purchased a Flowmaster cat converter to stop a check engine light from coming on. I also wanted some extra exht noise even though I only have a 231 V6. Mission accomplished on both.

The quality of this product is outstanding. I saw an increase in power at the top end and a 2-3 MPG increase. It was easy to install except that I run a header on my jeep and the bolt flanges don't allow the pipes to seal completely causing a noticeable leak. Added some gasket material at the union and now its good to go.
