The Helix Cams (great for all you Hybrid 2.5L WRX head guys out there) are finally back in stock!!!

Helix RNA Series Valvetrain and Cams- 2001+ Subaru Impreza EJ20 (non-AVCS) $999 shipped
The Helix RNA camshafts are designed specifically for high power Subaru applications without sacrificing drive-ability and streetability. The RNA cams work well on the 2.0 platform, with a minor reduction in low end torque while providing truly impressive mid and top end power gains of over 20+ whp, and truly come alive on larger 2.2 or 2.5 liter applications by providing the extra intake and exhaust that the larger displacing engines need.*
*Helix Valvetrain is recommended for Helix Cams.

Helix RNA Series Cams- 2001+ Subaru Impreza EJ20 (non-AVCS) $519 shipped
While it is highly recommended that these cams are used in conjunction with the Helix Valvetrain, they can also be used with your stock valve train (which allows for 10mm of lift).

-SPECS: 264 Duration, 9.6mm Lift,Titanium Retainers, Dual valve spring, with spring seats
-APPLICATION: EJ205 / EJ207 Non-AVCS only
-RECOMMENDED MAXIMUM REDLINE: 8500RPM (w/ Helix valvetrain and supporting bottom end only)
-This cam and valve train package in the 2.0L WRX heads w/ a 2.5L SB make peak power numbers that are actually better than many of the 2.5L STi motors that we have tuned with similar supporting mods.



New Helix V3 Downpipes!!!

Helix V3 Downpipe for 02+ WRX / STI - $199 shipped

The Helix V3 downpipe incorporates all the popular features of the V2 downpipe with the addition of an external wastegate provision. This provision allows for external wastegate gases to be vented back into the downpipe. Helix also re-designed the bellmouth to reduce production costs without sacrificing the SS304 mandrel tubing, high quality TIG welding, etc. The end result is a better downpipe at a lower price.



Helix Catted Downpipes for 02+ WRX / STI - $399 shipped

The Helix Catted Downpipe incorporates Helix Power’s first-rate bell-mouth downpipe, with the addition of a 200 cell Metal-Substrate high-flow catalytic converter and thermal barrier heat-shield. The 200 cell Metal-Substrate downpipe has been tested by us to yield 7-10whp over the factory twin cats, while able to pass stringent California smog standards on the WRX / STI. The thermal barrier heat-shield assists in rapid warm-up of the cat for maximum efficiency and helping to reduce engine bay temperatures.

Gruppe-S V2 Manifold - 02+ WRX / 04+ STI - $399 Shipped!
$575 Shipped for coated!

The Gruppe-S manifold is a 4 to 1 manifold designed to provide extensive midrange and top-end power gains. Our manifold features T304 Stainless Steel piping, mandrel bends, and CNC precision cut flanges. The 4-1 collector is cast to ensure the smoothest possible low rates. Strong gains in both HP and torque can be expected with the addition of the manifold, especially with high horsepower applications. The Jet Hot 2000 outside coating eliminates heat loss thus virtually eliminating low end power loss (compared to stock headers). These are the best coated headers we have ever seen; the coating is evenly applied with no bubbles and is absent from all bungs and threading. Includes all necessary gaskets.

The Crucial Racing 2000 outside coating eliminates heat loss from the exhaust gasses (as compared to stock headers). Because warmer air travels more quickly and expands more quickly, this helps to spool the turbo more quickly. More information on the coating is available here:
