STS 48 - External Wastegate

Wastegate STS Ultragate 38mm 7Psi Blk

STS Turbo systems overcome the challenges of traditional turbo installations by mounting the turbos at the rear of your car. This allows you to retain stock exhaust manifolds, catalytic converters, and mid pipes. Stock intake and throttle body can also be retained if desired. Relocating the turbos to the rear helps avoid adding additional heat under your hood and you won't have to worry about clearance or interference issues with the belts, pulleys, or accessories in the engine bay. You'll also get better weight transfer since the turbos are in the rear and not adding additional weight to the front of your vehicle.
