After i put it to the test I was blown away by the Gibson Performance Exhaust. The stainless steel construction is durable and rust-resistant, while the mandrel-bent tubing allows for smooth exhaust flow .The exhaust note is deep and throaty, giving my car a more aggressive sound. The only con I can think of is the installation process was a bit challenging, but well worth it in the end. Overall, I highly recommend this exhaust system for anyone looking to improve their car's performance and sound..
