So I've seen a few people on here have fitted them with the evotech tail tidy. However the bolt that goes through the tail tidy and into the bolt in the frame is a m8. I would assume these bolts from factory would be m8 hence the m8 nuts in the frame being m8. However the bracket that holds the spark exhaust on has a hole way bigger than a m6 but ever so slightly smaller than a m8. Did people have to widen this hole slightly? any help is much appreciated
