I'm well chuffed with the exhaust. Cost my £160.00 off of a guy off the RS Owners Club and is brand new

bargain.
A four incher would have been nice but couldn't justify the extra £140.00. The tail pipe doesn't actually stick out much at all and looks spot on to me. I've seen some S1's where the tail pipe sticks out a mile and looks really crap.
I'm not sure whether to take off the deflector or not. One it may leave a mark on the roof and two, it does help protect the sunroof. I might take it off when I do the full rebuild but will leave it on till then me thinks
