"I'm very pleased with the Gibson Cat-Back Swept Side Exhaust System. Excellent quality along with an easy installation." —Wilson A from Newry, SC bought a Gibson Exhaust Systems for a 2003 Nissan Frontier.
"Installation was a breeze. Instructions where easy to follow (had pictures). The sound is just right, sounds like my friends 350z. I have no way to measure HP increase, but there is a noticeable improvement in acceleration. My goal was to improve MPG, which have seen a 1-2 mpg improvement. Can't say enough about AutoAnything's custom support, every time I've called I've got someone on the phone very quickly." —Chuck J from Canton, GA bought a Gibson Exhaust Systems for a 2003 Nissan Frontier.
"I had my exhaust installed by a muffler shop because I didn't want to mess around with the old system. It sounds great and I have increased HP. I also like it because it's tucked in higher. Well worth the money!" —Dameon H from Portage, MI bought a Gibson Exhaust Systems for a 2003 Nissan Frontier.
