I have a 2009 Pontiac G6 GT. 3.5VVT engine. Local Dealer, Sacramento CA, suggested replacing the existing muffler with the AR25. WOW, the exhaust sounds great. I'd half expected to hear the car sound like a fart can, but boy was I wrong.........I've never been more satisfied with a product, than I am with the AERO Resonator.
