      Make More Power for More Fun. The cp-e Precision Atmosphere Turbo Base Kit will allow you to generate even more power. This Base Kit is designed to replace the exhaust manifold, catted down pipe and intake to get rid of all the factory restrictions.

      Re-Route Down Pipe. The "Reroute Down Pipe" is designed to reroute the external waste-gate exhaust back into the exhaust flow and will produce a loud, yet agreeable sound. The Down Pipe is manufactured in the USA from high quality, 3-inch diameter, T-304 stainless steel tubing for superior strength and enduring corrosion resistance. cp-e then completes their Down Pipes in their own Titan™ Uniform Satin Finish to further enhance its strength and appearance.

      High Flow Exhaust Manifold. cp-e engineered its exhaust manifold for the most efficient exhaust flow possible. Cast from 304 stainless steel for durability and strength, this exhaust manifold features extra O2 and EGT bung fittings allowing for the addition of additional sensors. The manifold is protected by a fully encompassing heat shield that holds the heat in the manifold and out of the engine bay to keep under hood temperatures down.

      Upgradable Modular Design. The included exhaust manifold was specifically designed with flanges that fit  Precision V-Band Turbo Housings as well as a Tial MVR External Wastegate. The use of V-Bands makes this Kit modular, so that you can upgrade your Turbo as money and time allow. The rest of the kit stays in place, you only need to replace the turbo itself to make more power. This set up is ideal for those performance enthusiast who need to quickly change turbos based on track or racing requirements.

      Calibration Required. Installation of this cp-e Precision Atmosphere Turbo Base Kit will require the use of a Handheld Tuner to reprogram the vehicles computer (ECU) for operation. By reprogramming your Mustangs ECU, you will be able to realize the full power potential that this Turbocharger Base Kit has to offer.

      Application. This cp-e Precision Atmosphere Turbo Base Kit with optional Down Pipe for use with Precision Gen I Turbochargers is specifically designed for use on 2015-2020 EcoBoost Mustang models equipped with the turbocharged 2.3L Inline 4-cylinder engine. Please note that no turbocharger is included with this Kit.

      Technical Note. This product is not legal for use in California or any other state adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.
