The decat downpipe reduces the back pressure, which results in more power and significantly more torque, and reduces the thermal load on the turbocharger. Made out of high-quality stainless steel, this downpipe replaces the OEM downpipe and fits perfectly.
The downpipe has a Diameter of 89mm, wall thickness 2mm.

MOSSELMAN tuning experiences
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!
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.
