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.
Quickly evacuating spent gasses through the downpipes increases the overall performance of your turbocharged BMW. Installing Active Autowerke’s N54 135i/335i performance downpipes result in quicker engine revs, and a noticeable increase in horsepower!
