Great Sound, Appearance & Performance
This is a great system for the GMC Terrain. Installation takes about an hour and half and there is plenty of adjustment to achieve a "perfect" fit since not all vehicles are created equal. To facilitate installation I fully inserted and tightened the forward Magnaflow pipe making sure the hanger rod was parallel to the bottom of truck in the hanger. Because of all the adjustment available you do not have to have this pipe loosely fit as the instructions would have you do it. After that, there is ample adjustment for leveling the muffler and setting height and protrusion of the exhaust tips. The engineering was well thought out. Appearance is great! The rear muffler is no longer visible and gives the vehicle a nice clean look from the rear. Tip height can be adjusted to personal preference, but be aware that the stock tips have 20 to 25 millimeter clearance with the top of the rear diffuser openings to prevent the plastic deformation due to radiated heat from the tips. Sound is a personal preference, and I like the sound of this system. It has a nice mellow sound at idle and does not drone at cruise. People tell me it sounds great on acceleration, but with the sound deadening of the vehicle it is hard to know that while driving. There is a felt performance improvement with wide open throttle. Just "floor it" and you'll feel it. I'm not sure if the performance is solely the result of the Magnaflow system. When the stock system was removed there was a "hot spot" on the top resonator just behind the outlet. The metal had turned blue indicating it had been red hot. This might have indicated an obstruction in the resonator that may have been also inhibiting performance.
