Expert's advice:

The N20 downpipe without catalysator has a diameter of 76,1 mm and can be installed on the N20 engines from the BMW 320i, 320ix, 328i and 328ix (F30, F31 and F34). The downpipe is completely made of acid resistant steel.

The downpipe without catalysator is necessary for Stage 2 tuning.

MOSSELMAN tuning experiences

  • Anders M.

    With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information sharing process was easy and hassle-free. Excellent customer service from Leon and his team!

    Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!

  • Rob M.

    Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!

    Visited Mosselman on May 24th for the chip tuning of my 135i, great result! The adjustment is great, when will you post the photo on FB :)?

    After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
