I installed this myself in about 2hrs.This system has great ground clearance, but the muffler sits too close to the floor and rattles against the floor. I will have to put a dip in the inlet & exit pipes at both muffler joints to fix this clearance to floor issue. I love the sound shifting through the gears at lower speeds. 75mph on the highway is a little loud inside the cab.I can't wait to take the top off cause then it doesn't matter ! Great power, and I think I picked up a little MPG too !
Improvement over stock is significant

- Well designed cat back that fits just right. - Installation was fairly simple. You'll need to cut the stock exhaust at the bend in front of the axle. - New bolts for the front pipe that attaches to the catalytic converter were not included. You'll need to purchase some new ones after you destroy the old rusted ones during removal. - Sound is nice, a little louder than stock, not bothersome at all. - I gained about 1.2 hwy mpg - Better throttle response, power increase difficult to tell.
