Competition Series 4" Catless Downpipe

The Evo Raceworks Competition Series 4" Catless Downpipe is engineered to significantly increase horsepower and torque by eliminating the restrictive factory catalytic converter. Constructed from 100% 304-grade stainless steel, it features 4-inch mandrel-bent piping and 100% TIG welds for superior quality and durability. The precision CNC-machined V-band flange ensures a precise fit to the factory or aftermarket turbocharger. It incorporates a stainless steel flex section, mirroring the factory design to prevent undue stress on the exhaust system, turbocharger, and exhaust manifold, thus enhancing overall durability. Optional features include a high-temperature black thermal coating to reduce underhood temperatures, an additional O2 sensor bung for wideband sensors, and an EGT sensor bung for exhaust gas temperature gauges. Compatibility includes the 2011+ BMW 535i (F10) and 2011+ BMW 640i (F12/F13) with the N55 engine. It is compatible with both factory and aftermarket exhaust systems.
