I've got a jag x type 2.5 and I'm going to do a cheap exhaust replacement. I've got a 4 inch jap can coming soon. I'm looking at shortening the exhaust length by nearly two meters. So my new can will sit mid way under the car roughly 1 meter away from the front wheels. It will be clear of fuel lines and tank. There's sufficient space for it too. I've got a detachable silencer and packing to make it quieter for MOT's. Just wondering if there are any issues and would it pass a MOT?
