Gruppe-S V2 Manifold - 02+ WRX / 04+ STI
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. Includes all necessary gaskets.
Helix Top-Mount-Intercooler - 02+ WRX/04+ STi
The massive bar and plate core allows efficient cooling of the intake charge with minimal pressure drop. 25 + degree (F) intake charge temperature reductions are realized over the stock TMIC – helping to both increase power and reduce risk of detonation.* Included is a cast-aluminum Y-pipe, silicon hose, and the cast end-tanks are CNC machined to ensure optimal flow characteristics. Dyno-testing has yielded over 15whp gains with even greater performance gains in real world conditions.
Helix Catback Exhaust - 02+ WRX/04+ STi
-Finally back in stock!!!
-Full 3.14" Stainless Steel Mandrel Bent, polished piping.
-One resonator and silencer included.
Helix (Stainless) - US Spec Catless downpipe- 02+ WRX/STI
-This downpipe features a cast bellmouth which provides the absolute maximum exhaust flow and minimum back pressure by allowing the wastegate gases to exit without disrupting normal exhaust flow.
-The piping is full 3" Stainless Steel (304) polished, and the package includes gaskets & bolts.
-This downpipe replaces both cats and is designed for USDM fitment only.

Helix Catch Can
The Helix Catch Can is designed to trap oil moisture and blow-by caused by normal engine operation, especially in turbo charged vehicles. On your factory vehicle, because of emissions regulations, the waste oil and sludge is generally re-routed back into the intake stream. This debris will tend to accumulate inside the intake tract, intercooler, turbocharger, as well as be ingested into the engine during normal combusion process. Needless to say, this sludge and blow-by will hurt the performance of your vehicle. The Helix Catch Can eliminates this problem by trapping such debris and insuring optimal horsepower and longevity of you vehicle.
