Customer Reviews

Awesome Exhaust Review by Matt
Though the price makes you think this is going to be a little on the cheap side, this is quite possibly the nicest exhaust I have ever purchased. I bought this for my 04 GT to replaced the cobbled up weld-in flowmasters on it and let me tell you it is an amazing difference. The sound is very similar to borla stingers or magnapacks. There is no real drone on the highway just a really nice sound. I usually judge a company by the hardware they send with their products and the clamps that came with this should be standard equipment for all manufacturers. The tips are a little on the big side but they fill the cutouts in the bumper very well and look great (especially once they are polished). If you are on the fence and looking for a nice exhaust and don't want to pay the big name premium, this is hands down the exhaust to go for. Its loud, but still sounds amazing. I highly recommend this product. (Posted on 6/11/15)
