I am selling 2 down pipes with the secondary cats removed but the work cannot be seen when on the car to keep Mr MOT man from seeing anything. pipes have 21k on them. Came off a 2012 R172. It means you have the originals for the car encase emission rules get tighter in the future. Easy to fit as I done them in about 2 hours using car ramps. Thanks for looking £375 plus postage.
