mbrp installed now problem

[MJP8540]

I installed a turbo back mbrp today. Gutted the cat also. Now at wot I hear and feel a grindin noise until I let out of the throttle. Sounds bad. Not like something rubbing more like motor or drivetrain? Didn't happen until todays install. Ideas??

any other info where is sound coming from? double check all your work, could most likely something simple.

Not sure if your system is different than mine because I have the cat delete kit. BUT right behind where the cat was there is a hanger. Mine was touching the frame rail. Cut that steel rod a little shorter and all was perfect.

Look for the exhaust system hitting the body or frame.
