I highly recommend getting a welding shop to weld mushroom ends into your hangers. I bought a Rev9 downpipe for my MK7 GTI. It didn’t have the mushroom ends either. The downpipe bolted up perfectly fine, but it did start to wiggle itself out of the bushing because of having no mushroom end to prevent it from wiggling out. It ended up tearing up the bushing and rubbing metal to metal, making a bad squeaking sound while driving. So I got mushrooms welded on, and have had no issues since then. I’ve had it for 3 years now.
Humble Garage Hell yea, ordered yesterday, deals too good to pass up! Getting accessport this week. Looking forward to some sound clips, and future exhaust build! Look into EQT tuning, their stage 2 tune with crackles seems to the be the truth
