I've had a bit of a nightmare with my exhaust, the exhaust broke away from the the mount and it ripped a hole in my exhaust which I've had repaired. However, my next issue is I need to replace the lower gearbox mount and the flexi pipe.. I've been told the gearbox mount is easy but the flexi pipe is hard work. How much should I be looking to pay for a new flexi pipe as I already have a decat.
