This isn't the first time reading about the subframe issue on a car that had an aftermarket exhaust. Perhaps it isn't bad installation, but very particular bolts in respect to torque- or perhaps the bolts have issues if they are EVER removed. Sounds like I'll spend a couple more bucks and have exhaust installed for $200 at the dealer.

BTW, have you watched the M exhaust video? Full on burn outs. Redline shifts. The car can handle it, no problem. If you've messed with the subframe bolts and incorrectly torqued them and there is breakage, no one to blame but your installer.
