This is a video tutorial of installation of the Macht Schnell N54 Catless Track Downpipes.

Stock downpipes cause a major restriction in exhaust flow coupled with their small 57mm (2.25″) 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″) N54 Catless Track Downpipes allow instantaneous turbo spooling and ultra-low backpressure proving significant hp/tq gains that can be felt immediately after installation.

Downpipe Features:
- 76.2mm overall diameter, eliminating restrictive factory pre-cats and crush bends
- 100% T304 Stainless Steel construction, using mandrel bends
- Precision TIG welded joints
- Heavy-Duty Stainless V-Band/Exhaust flanges
- Heavy-Duty locking fasteners and exhaust gaskets included
- Factory O2 locations retained with Stainless Steel bungs
- Pre-installed Stainless EGT bungs for easy thermocouple mounting
- Reduced underhood temperatures

Models Supported:
2007+ 335i (not for xi models)
2008+ 135i
