  1. Awesome product 5 Star Review

    Posted by on 15th Dec 2015

    I bought this CAT to replace a Euro pre-muffler I had installed. I loved the pre-muffler's sound and performance, but I could NOT stand the smell from the exhaust at stop lights. Having a cabriolet made it worse.

    This sport cat stopped the smell 100% and the performance is equal to what I had from the pre-muffler from what I can tell. The sound is slightly quieter than the pre-muffler, but I like the tone even more.

    The installation of this part was very easy. It fit the car on the manifold side and the muffler side perfectly. I did have to make a couple of the holes in the gasket on the manifold side a little larger to fit the bolts through, but the fit of the pipe itself was spot on.

    The build quality on this piece is fantastic and it looks beautiful! I don't know if the chrome will stay chrome, but for now it's quite shiny!

    Overall, I couldn't be happier with this product.
