All I have to say is WOW love it

Yes it dose sound amazing! I have the GMMG on my car with the large tube SLP's. Sounds so wicked. I get so many looks and people telling me how good the car sounds. Plus going under anything with an overpass/tunel/parking garage is fun! Adam :-)

Re: Just got my gmmg installed
interior noise at highway speed isn't that bad at all no drone at all just a nice rumble, but when you step on it roars, and sounds amazing. I used to have a B&B catback on my car before which is one of the most expensive 4th gen catbacks you can buy, and it sounded like crap compared to this barely loud at all. I will get some pics for you in a couple days ill get some under the car too, because I have to replace a section of pipe that the muffler shop messed up, because it's been bugging me.....apparently their tubing bender doesn't like 3 inch exhaust, and they tell me this after basically destroying the $17 section of pipe I just bought, at least they didn't charge me. Very easy to install the only problem is that THE I-pipe is like 10 inches to short. overall though extremely happy with my purchase I have been wanting this exhaust since I first got my car nearly 4 years ago
