AWESOME, this exhaust is exactly what I needed. I would recommend this to anyone who has an SS, it sounds so good, yet not overbearing. Throttle response, mileage and horspower increased more than even my sceptism would or could believe. I have other mods done, but this just put everything over the top, thanks to ALEX and all the GMS company....I AM VERY SATISFIED AND HAPPY with this purchase!!!!!

I love my new Granatelli exhaust, it is everything they said it was and more, the sound is great and the performance is excellent...

Big difference driving up the Camarillo Grade southbound toward Thousand Oaks have quicker throttle response with more power. Granatelli's exhaust systems are MUCH better than the "top of the line" GM installed exhaust system with their crome tips. It's a good thing that I went under the car because the GM exhaust was already rusting....But on a 2010 Camaro 2 SS RS with all the goodies I thought I had all I needed. Nope! This Sounds much better and more power. I'll get back to this comment on gas mileage after a few fill ups. EVERY and I mean every purchase my neighbors and I have made have been hassle free. We're all happy and trying to outdo each other. I love all the smiles, headturns and stares. I came across another 2010 Camaro that walked away from me... next stop light she said she had Turbos..... from Granatelli and that she "Loved it". BTW we never exceeded the legal safe speed limit nor did we break traction at any time.
