As more performance parts come out for the N14 and N18, one of the things you need is a catless downpipe to run the boost you want with a tune. Milltek has been in the game for a long time and has come out with version 2 of their downpipe. The turbo mating surface is now cast and machined to a high tolerance for perfect fitment. The rest of the downpipe is robotically welded to ensure quality on every weld. The pipe is stainless steel and mandrel bent to maintain the large 2.5 DIA bore of the pipe. Milltek says you will get a 27bhp gain, but that can go up with a good tune. Great flow, good fitment, and a low price! All winning features in this downpipe. We also have a version with a cat for states that require it. You may get a check engine light unless the car has a tune.

Note: Not legal for on road use or use in California. For off road use only.
