5Super awesome product. Easy to install. Perfect fit.
By 73CAM
As the title says, "Super awesome product. Easy to install. Perfect fit."It's a Flowmaster system, sounds like a Flowmaster system, but it's not the loudest. I'd say this one is a medium loud system. Go for some 2-chambers or a 3" system if you want to disturb the peace.Love the horizontal, rear facing, polished tips with this system.Installation TipUse the supplied clamps first, then drive, then weld. Driving for a few days may reveal clearance issues with your placement.For the four mounting holes that go through the rear seat's sheet metal, I recommend drilling them a bit lower than you might think in order to allow for tail pipe clearance. I first mounted mine too close to the undercarriage, and while the mufflers were up nice and tight, the tail pipe was vibrating against the frame rail above the rear axle.
