Kwan88 Posted December 5, 2020 Share Posted December 5, 2020 I have a B8 S5 Convertible with an aftermarket longlife exhaust from the downpipes back. It seems the downpipes cats were cut off and a flange to X-pipe straight through to the back boxes were installed. In a quest to get quiet down the car, Basingstoke Longlife suggested / tried to install new back boxes which made little difference and after over 5 visits, and as the nature with aftermarket its not entirely right. So I have brought the oringal S5 OEM exhaust which has the 2 back boxes and the central resonator, but after going to a number of custom exhaust shops, it seems they find it hard to quote or are unable to help as the oem resonator pipes does not marry up with the aftermarket x-pipes. In my basic mind, I would have thought its just a bit of welding and a short bend of the pipe from the x-pipe to the oem resonator or cut the x-pipe completely and run a straight pipe from the down pipe flange to the oem resonator. But from custom exhaust places it seems a difficult job. I am located in Berkshire and was wondering if there are any recommendations. Only one quote so far of over £400? Regards.
