OE End Silencer Upgrade for BMW 3 Series E90 E91 316d 318d 320d

Give your 2.0d 3 Series a refined, sportier tone with the original BMW rear section, built in stainless steel with twin 74 mm polished outlets. This factory-spec axle-back backbox is designed to reduce restriction, improve exhaust flow and sharpen throttle response while keeping motorway comfort and zero drone. It looks right, sounds right and fits like it left the showroom that way.

We have installed this OE system at MJ Modifications in Warwickshire and customer feedback has been consistently positive for fitment, tone and longevity.
