Hi eveyone.Just a quick question about exhaust systems.Does anyone know of any good ones for a MK3 8V GTI?I've just bought the car and it has a DTM backbox on it that doesn't fit very well and is basically sh!te so i want to change the system.Also,does anyone know about de-catting them as i was wondering what would happen at an MOT test due to emissions,etc.Many thanks appreciated in this matter.Feel free to e-mail me personally on this
