"This comp. was there when I lost My order and I had only my ebay receit. Thay founded my order and sent out right any Thanks" posted by: zzsplash on March 11, 2014

"I opted to have this muffler professionally installed (welded on) because it didnt have a hanger attached to it. The frost heaves and dirt roads that we have to deal with in northern New Hampshire would guarantee it would fall off with just clamps holding it in place. The finish and quality is really nice and it looks good on the car the duals make it look unique as well. Its my 19 year old sons car and he says its too loud and well be having a resonator installed when hes home from college during Christmas break. The bottom line is this take into consideration the cost of a resonator and professional installation before you buy it it might be cheaper to buy an entire exhaust with a resonator included. Fortunately this car had a brand new cataytic converter and mid pipe being installed at the same time paid for by the dealer so the cost of the muffler install was minimal." posted by: NEDiver on October 9, 2013 view all 5 reviews
