I treated the rear muffler mounting as a seperate exercise, its position being critical to getting the tailpipe right. Being a 2800cs, the mounting tabs on the body are closer together than 3.0 I suspect, which this system is designed for. I hung it from 2 reinforced rubber strips which ended up at about 20-30 degrees splayed out. I welded a tab to the tail pipe, felt it needed support to avoid swinging around. Then adjusted the tail pipe to fit round the spare wheel well. The sealing ring allows quite a range of adjustment without leaking. The down pipes don't end up central to the body, about 30-40mm to the right, but using a transmission jack to hold the centre muffler in its best position and height, and finessing the distance the pipes penetrate at the downpipes and the rear muffler, it all came together nicely. The flange joint between muffler and resonator also allows a wide range of adjustment without leaking.
