Borla Cat-Back And Axle-Back multi-core technology to unleash hidden horsepower. Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability.
I had some Steeda axle backs on my 2019 Mustang Gt and I wasn't crazy about the sound. They were loud but the sound was a very unrefined tone. I upgraded to this catback and the spund is exactly what I have been looking for. The car also feels like it has much better torque since taking off the factory suitcase resonator. Favorite Mustang sound I've ever heard.
