Active Autowerke F87 M2 Signature Turbo-Back Exhaust System (11-042)
$3,450.00
This system is the result of countless hours of R&D by Active Autowerke to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, Active Autowerke has created a modular exhaust system that will provide enough flow to support power levels way above the stock M2.
When installed as a complete unit, the exhaust diameter of this system never shrinks below 3.5”. Active Autowerke’s catless downpipe flows seamlessly in to the mandrel bent mid pipe (with no diameter change) all the way back to the rear section. The rear section splits from a single 3.5” pipe in to dual 3.5” pipes; one of which is valved and leads straight to the exhaust tips with the other leading to a straight through muffler that reduces noise levels when the valve is closed. 3.5” legs were used on the Y so that the exhaust gases would have minimal restriction even when the valve is not open. Although the use of stamped Y-pipes has become popular, they often contain pockets and obstructions internally that promote turbulence. The Y-pipe by Active Autowerke is hand built to maintain maximum exhaust velocity throughout the entire system.
