Just found a pin-prick of a hole where the double bends are on the rear of the exhaust. Exhaustive trawling after being told the genuine part is £450:bang: , I decided to get some stainless quotes and boy, it excites me!! I have just had communication from Longlife exhausts (link below) and have been quoted £299 for the system (upto the cat) and an extra £59 to take the cat out all together, I find this an amazing price, I will let you know as soon as I have it fitted!
