I have a GT86 2015 and have just noticed the exhaust tips or both sides are touching the rear diffuser which doesnt seem quite right. Is this an issue that needs to be resolved or is this alright.
It's not alright. There are 2 things that you need to check.
1. Check the bottom of your exhaust back box. Does it have bump/scratch marks? If yes, the exhaust has lifted because someone lowered the car and went fast over a speed hump which hit the back box.
2. Check the rear bumper. It might have been in a back end accident or has sagged or had been removed at some point and not mounted back properly.
