When I had my Paj engined Vogue SE, it still had the petrol front box on it. I bought a VM downpipe and front silencer and managed to cut and shut it. Trouble was, all the vibration used to crack the downpipe just below the manifold so I ended up scavenging the local tyre & exhaust centre's skip for a suitable flexi-joint. The same exhaust has now been on it for 4 years with no probs.
