If your Silverado\/Sierra 1500 features factory dual exhaust bumper cutouts, you will need a dual-exit adapter or exhaust tip extensions to align properly with the bumper bezels.

Unbolting the front driveshaft flange or dropping the crossmember temporarily provides the necessary clearance to slide the OEM downpipe out without cutting the vehicle frame.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Will this kit clear the rear shock absorbers and spare tire heat shield?\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eA5:\u003c\/strong\u003e Yes. The 3\" mandrel-bent piping is routed along the factory exhaust path to clear the rear axle, shock mounts, and spare tire heat shield.
