Active Autowerke Downpipe - BMW E9X 335i N54 07-09


Product Description

The OEM BMW 135i/335i exhaust is designed to restrict noise and heat. As a result, when the BMW 135i/335i N54’s turbos spool, the impeller wheel speeds are limited by exhaust back pressure within the factory system. Eliminating some or most of this exhaust back pressure allows the turbos to spool that much faster and effortlessly.

Installing Active Autowerke’s N54 135i/335i performance downpipes result in quicker engine revs, and a noticeable increase in HP.

Customers will experience a faster, more responsive BMW N54 engine, as the turbo impeller now has the ability to spool much quicker. The end result is more power from your BMW 135i/335i exhaust. Made from T304 stainless-steel with 1.50mm wall thickness throughout ensures owners are left with a durable exhaust that will continuously provide trouble-free high performance with longevity to match.

Note -

Will not fit Xi models.
