I researched many exhaust systems and after a lot of searching I decided to choose this Corsa sport exhaust for my GMC Sierra. Installation was easy doing it myself and once installed I couldn't be happier. It's aggressive on startup but mellows out to a deep sounding exhaust at idle. Under acceleration was a bold, aggressive tone that woke up even more power the stock exhaust was hiding in my truck and the no drone while cruising is exactly as stated. Perfect exhaust. Highly recommend.
Second Borla purchase
Love the sound and chrome tips. Installation instructions should address the driver's side pipe better. There is no mention of additional sockets/tools needed to install the hanger for the rubber mount. Having done this before on an '08 model, I had the tools. If not for that I would have had to make a trip for them. More difficult on the garage floor but can be done.
