Greddy SE exhaust fitment 76mm??
 

I think 76mm 2.75 pipe or if other clearance similar from other single exhaust set up?

Previously without the bracket/hanger had the muffler sit center but had the following problems
- rubbing frame on hard turns and any full wheel lock turning.

Now it still rubs frame sections at random areas but much less and seemingly lighter than before but muffler not sitting straight. Somethings going to give eventually... exhaust or frame? Or will it actually grind enough to the point where no structural compromise occurs?

Is it the hangers? if so which are recommended or should I acquire some oem ap2 triangle?

might need some new hangers or stiffer hangers. but where is it rubbing?

around mid muffler/axle back subframe area

I have an appointment at an exhaust shop tomorrow and see what kind of adjustments can be made.
