eas | Macht Schnell 3" ThermalCoated N54 Catless Track Downpipes *IN STOCK*

Applications which require a significant surface temperature reduction as a result of high temperature heat soak will benefit from ThermalCoating. Designed to operate in temperatures up to 2100 F, and meet 3000+ hours of a standard ASTM B 117 salt spray testing, this process will protect the substrate from thermal fatigue and oxidation as well as oxidation scaling while reducing skin temperatures by as much as 54%. ThermalCoating meets U.S. military specification MIL-C-81751B for metallic-ceramic coatings, including FAA approval.

With a maximum output of 306 hp from 2,979 cc the 135/335's N54 powerplant ensures exceptional driving dynamics at all times with all the power of a much larger normal-aspiration engine. Twin turbochargers each forcing compressed air into three cylinders ensure a standard of spontaneity never seen before in a turbocharged power unit. The big advantage of these relatively small turbochargers is their low inertia, avoiding excessive "turbo gap" the moment which usually passes by until the turbocharger builds up its boost typical of a conventional turbocharged engine. On the road, therefore, the turbocharged power unit of N54 variant offers all the power and performance of a much larger normally-aspirated engine.

Stock downpipes cause a major restriction in exhaust flow coupled with their small 57mm (2.25***8243 pipe diameter and numerous crush-bends with factory pre-cats squeezed in engine compartment. This results in excessive backpressure and excessive heat, which ultimately affects overall performance at all RPM loads.

Macht Schnell's 76.2mm (3.00***8243 N54 Catless Track Downpipes allow instantaneous turbo spooling and ultra-low backpressure proving significant hp/tq gains that can be felt immediately after installation.

Mandrel-bent T304 Stainless Steel tubing is used to ensure constant exhaust flow is achieved by eliminating any restrictions, resulting in maximum gains and noticeable sound during turbo spooling. TIG-welded construction and Stainless Steel V-Band/catback flanges are durable as well as pleasing to the eyes. Heavy Duty exhaust gaskets and Stainless locking fasteners complete the package.

Stainless O2 sensor bung locations are mounted in the factory locations while introducing additional stainless steel thermocouple bungs for those monitoring EGTs.
