Great Exhaust

Coming from a titanium Tomei which was LOUD. This is a bit quieter than I thought it would be but I love it. No highway drone, no obnoxious cold starts in the AM. I am running this with a 20G and ELH, it is the perfect setup for a DD.

Everything it says

This exhaust was exactly what I wanted... give me a little more growl out of the boxer, but not obnoxiously loud, inside or out. Definitely feel more low-end jump as well. Great deal for one of the less-pricey exhausts on the market. Still debating if I want to leave the tip shiny stainless or paint it matte black to match the Cerakote.
