RK Autowerks Mandrel Bent 1 Piece Downpipes

Hey guys,

We wanted to offer the community a reasonably priced set of downpipes. MSRP on these is $1500, M5post special price is $1000+shipping.

Nobody on the market has a true 1 piece mandrel bent setup, you'll notice with everyone else that they have many welds. These welds can fail overtime and cause flow disturbances. You'll notice with ours the only welds are for the flange, reducer, O2, and the mounting bracket.

The RK Autowerks catless downpipes eliminate this restriction allowing for quicker turbo spooling. The lowered back-pressure results in significant horsepower and torque gains that can be felt immediately. Having been designed using state of the art 3d scanning and prototyping ensures that all of our downpipes fit the customers car just like OEM downpipes do.

Our downpipes and mandrel-bent T304 stainless steel tubes with CNC velocity stack flanges at the turbo mount. Due to our pipes having only 2 welds we’ve eliminating any flow disturbances resulting in maximum gains. Nobody else in the market offers a setup with a nearly full 1 piece mandrel setup. TIG-welded construction with v-band flanges ensures that there will be no failure down the road for all our customers.

Stainless O2 sensor bung locations are precision mounted in the factory locations.

Downpipe Features:
– 3.00″ overall diameter
– T304 Stainless Steel construction, using mandrel bends
– Precision TIG welded joints
– Heavy-Duty Stainless V-Band/Exhaust flanges
– Factory O2 locations retained with Stainless Steel bungs
– Reduced underhood temperatures

Models Supported:
2012+ BMW F12/13 M6

Purchase these with a set of intakes and receive an additional 10% off!
