I did this mod like 2 months ago, it is an okay mod for 100 bucks, it is a simple cutting and welding job, however I am already bored. It adds the TUM noise they are talking abt while shifting but it doesnt increase the sound that much.. so either I am getting a catless down pipe for performance or switching the stock mufflers with strait pipes.. but I dont think I will be spending 1k or 2 for a pair of mufflers..
