Any one else have an issue with a 2.5 inch catback rattling on there rear axle?
All insulators look ok
I'm on ark stp coils fully lowered and have the gmpp catback
Issue only started Happening when I swapped out the rear axle to a 2.4 rear beam with calipers for my rear disc conversion, also installed the zzp longtube at the same time

I hopefully have temporarily fixed it with some
Zipties but haven't taken it for a spin yet

Any permanent solutions? I've herd of this happening with a 3 inch catback and being
Lowered just not a 2.5

 

As long as the exhaust is not completely resting on it, take a piece of 1" heater hose, spit it down the middle with a blade, zip tie it to where the exhaust is bumping, problem fixed That's what I did based on some advise I saw on here one day and it works great!

 

Never thought bout that, will have to try it out,
And it's definitely not resting on it, just does it when u cone to a stop with my foot on the brake and with it in drive it'll rattle, have to throw it in neutral for it to stop, also happens if I'm stopped with the ac or heat on, turn off the blower and the rattle stops

 

ZiP ties didn't work lol, will be trying the heater hose tomorrow
