Clearly you pay more for a Borla Cat-Back system than for competing brands. When you want the best though, there is no substitute. The Borla "S" type Cat-Back system brought my 2012 Mustang GT "5.0" to life. I had previously installed a Cold Air Intake System, a Larger Throttle Body and Accel Super Coil on plug kit. Installing the new exhaust system seemed to allow everything to get back in sync for massive air in and massive air out with extreme power in between. I love the sound and the look of the 4.5" tips. My opinion, you either hava a Borla system or you don't and Auto Anything had the best price.

Great sound!

Installed this on my 2011 Mustang GT 5.0. The sound is awesome. People always turn their heads to get a glimpse.

The exhaust was the little piece that made the Mustang that much better!
