Mine scrap and im still stock height. Your stock hangers might be wored out like mine was (pictures below of the results) . What you can do is stop by your local NAPA and buy some new hangers. I believe they sell them for $5 something each. Its better than ordering online and waiting for the USPS man.
Reason:
1. Shop did some bad welding on the rear part of my mac catback
2. My hangers were shot.
Caution: the following picture are mind blowing. The exhaust is hanging like a noob installed it. But, my hangers was shot and i was semi-new so i said F-IT and installed it anyway. Potholes and dips was owning my poor 4x4
How i fixed my problems.
1. Brought new hangers.
2. Removed the midpipe than reinstalled but only finger tightening the bolts
3. After finger tightening get a floor jack and jack up the exhaust abit than start tightening up the exhaust system.
I had 235235 exhaust combos on my car and the one i had problems with was the o/r prochamber.. that box would scrap everything.
