BLOX Racing’s 3” turbo downpipe kits for the 2015+ Subaru WRX VA are now available, exclusively through Motovicity Distribution.
BLOX Racing’s 2-pc downpipe kit is made using high quality, T304 stainless steel tubing.  Tubing is mandrel-bend and TIG-welded.  The thick flanges provide additional durability and reliability against leaks and cracks.

BLOX Racing J-pipe kis are non-catted and non-resonated to provide maximum turbo exhaust flow and increases in horsepower and torque. Manual transmission only.  Tuning is required after installation.

BLOX’s line of MLS stainless steel gaskets are the perfect solution for inferior turbo gaskets that do not properly seal or end up breaking a part and causing leaks. BLOX MLS gaskets are heavy duty and intended to withstand the rigors and high heat temperatures of turbocharged engines. These high quality, premium gaskets are constructed from stainless steel and feature 6-layers of durability and reliability. For additional assurance and peace of mind, each MLS gasket is secured with stainless steel fire-rings. Once the gasket is installed and properly tightened, the fire-rings crush and create a stronger seal. [ORDER HERE]

BLOX Racing’s charge pipe kit replaces the factory’s restrictive hot side pipe on the 2015-2019 Subaru Impreza WRX. The factory charge pipe actually restricts air flow because of the internal ridges and uneven and narrow bends. This kit has been designed to eliminate these factory flaws and provide increases in air flow and performance.

BLOX Racing’s new charge pipes are CNC machined and mandrel-bent aluminum then powder coated for durability and to help reduce heat soak. BLOX Racing includes a CNC-machined turbo adapter flange and high density, multi-layer silicone couplers and all necessary clamps to provide a true, direct bolt-on experience.

Charge pipes are available in powder coated black and red.  Couplers are only available in black.


BLOX Racing’s EGR Block-off is CNC-machined from billet aluminum and is designed to eliminate the OEM EGR system. By eliminating the exhaust gas recirculation that is dumped back into the cylinders, the engine runs cooler overall. In addition, less carbon is deposited which is commonly associated with stuck valves. [READ MORE]


BLOX Racing’s Pitch Stop Brace is CNC-machined from billet aluminum and designed to reinforce the OEM’s mounting brackets.

2015+WRX and STi, unfortunately, are notorious for being designed with weak and thin brackets. Because of Subaru’s design flaw, engine movement or pitch from normal driving, placed too much stress on these points that they bent or tore.

BLOX Racing’s Pitch Stop Brace reinforces these points helping to greatly reduce the amount of flex or pitch. The thick 10mm braces tie in the mounting brackets to the firewall and also acts a clutch master cylinder brace.

BLOX Racing also includes a brand new, stainless steel clutch line, fittings and hardware to make installation easy and quick.


BLOX Racing’s Big Tube turbo manifold is available for Subaru Impreza WRX FA20DIT.  This high performance replacement features larger tubing than all other competing brands in the market.

The FA20DIT Big Tube Manifold features 45mm piping from start to end and 11mm thick flanges.  The ports have also been opened up to 41mm at the head flanges and 36mm at the turbo flange.  In addition to the “big tube” manifold primaries, the larger port diameters allow for greater flow and power production from the OE turbo or similar size aftermarket unit.

Manifolds are constructed from Schedule 40 T304 stainless steel and TIG-welded.  The Big Tube Manifold retains the OE original equal-length (EL) design, fitment and turbo placement.
