If you have an aftermarked exhaust on your RS4, what did you do with your original OEM exhaust?? Have you kept it or thrown it away?
Reason I ask is I am going to get a milltek non-res soon (not sure if valved or non-valved yet!) I've heard its a nightmare to take the OEM exhaust off neatly and it has to be CUT off in pieces!??

Am wondering whether I should retain the backbox with the valves to put on later so I can sell the car in an original condition and also sell the milltek or should I just ditch the original system and stick with the new one / sell the car with the milltek on it in 2 yrs time.
Cheers
