Pipes are on and fouling

I got round to trial-fitting the pipes so I could have the cans welded on. fitted them up okay but one is fouling on the rearsets.


So I can't line up the cans.

I've got two options - take a hammer to the expansion chamber to give it some "remodelling" or get a new set of rearsets. Had a think and I'll be getting the new set of rearsets.
