I've done some research on the matter but really can't seem to find a suitable answer. Basically I'm running my r53 with a magnaflow r50 exhaust on it, I've been doing this for a while with no real problem except it seems to rattle a bit against the heat shield. I'm almost sure it's due to the fact that I modified the r53 hangers to work with the r50 exhaust and it hangs just a bit crooked. Anyways the occasional rattle is starting to get on my nerves, I know some others have swapped the r50 hangers onto a r53 but I really can't find a good outline of how they did this and where the mounting points should be. Can anyone help with this.
