Last night I installed my MAC mufflers. This is the first install that I have completed on the '09 and it turned out really well. Today I got back under there and made sure everything was tight and sitting just right. I've gotta say that the end result was very impressive. I love the deep tone that I get now. It's not much louder at all at idle but you can really tell the difference especially when you give it some gas.

 

Yes!!!! I love my MAC Prochamber and MAC Catback! I tried Flowmaster Super 40 mufflers and I liked them with the Prochamber but when I strapped a MAC Catback on it I felt the power difference and I love the exhaust notes it puts out. Ive heard all of the other systems and I looked up flow charts for the mufflers and MAC impressed me the most. Price/Perfomance
