Borla Exhaust Systems Reviews

Great product!

Reviewed By Emil M (Valparaiso, IN) Reviewed for a 2014 Audi S4 —5/9/2016 6:50 PM

Had the Borla system shipped directly to my Audi dealer (Team Imports) for installation. At installation the entire system was laid out, and I was called to check the system. It looked perfect. After the installation was completed, the technician spoke to me and was extolling the quality, fitment, and engineering of the product. The service adviser stated that he was going to recommend Borla exhaust systems to Audi owners looking to upgrade to a performance exhaust. The sound is great!
