I really hope you're right, I do not feel like pulling the motor again. Got a few other possible culprits to cross off before I get to that.

Pretty sure btr has different springs rates. Also like I said. I went through 3 sets before I found one with actual correct pressure

@98 Saleen Cobra Well definitely an issue with the cats, driver's side honeycomb is broken in half. Sorry for the pic quality, my Whistler borescope is old.

Midpipe is at my buddy's fab shop right now getting "fixed". Should have it back on the car tomorrow, along with a new half shaft and LPW diff cover.
