Exhaust / Rear Block

[gmyeah]

Just want to make sure I'm thinking all this out, but there's no issue with adding a rear block on a 2015 4x4 sierra 1500 with respect to the exhaust, right? I'm considering putting on a Borla GM exhaust (dual tips out the back) and if the rear blocks lift the rear of my truck up 1" from stock or 1.75" from stock....my fear is that the tips coming out the back will be too far below the bumper. I've noticed the hangers are attached to the frame....so I'm assuming the exhaust comes along for the ride and it should still remain the same distance from the bumper regardless if its stock or raised a bit. Sound right?

You are correct.

Adding a different size block wont change the height of the exhaust relative to the frame and body/bumpers. Basically all you are doing is pushing the rear axle down more giving extra suspension clearance.

 

If you added a body lift, then the exhaust would seem like it was hanging lower because that increases the gap between the body and the frame.
