I just got a 2004 Jetta BEW engine code and I have been looking for a 2.5" downpipe and cant seem to find one. Is it my best bet to buy a flange and have one made at an exhaust shop? Also, I am trying to find out what "level" of tune I should do if I am keeping my stock turbo and adding a 2.5" downpipe with high flow cat and no muffler? My goal is better mileage and a little more power while keeping the reliability, and durability of the TDI. Any other suggestions would be awesome! Thanks!
