Description

Take your turbocharged Boxer powerplant to the absolute limit with the Kakarakis Performance Turbo Exhaust Manifold with Up-Pipe designed specifically for the legendary Subaru EJ20 and EJ25 engine family. Engineered from the ground up using advanced thermal dynamics, this manifold completely replaces restrictive factory headers and crossover pipes to maximize exhaust gas velocity, drastically reduce turbo lag, and unlock massive horsepower potential under heavy boost.

High-Flow Boxer Geometry & Perfect Balance
Engineered specifically for high-output motorsport applications where balancing exhaust pulses is critical for performance and engine safety, this manifold utilizes a specialized equal length piping configuration. This innovative layout completely eliminates exhaust gas interference between opposing cylinders, maximizing the scavenging effect and ensuring balanced thermal loads across both cylinder banks. The system comes complete with a precision-engineered, high-flow matching Up-pipe to guarantee a seamless path straight to your turbocharger.

Premium Material Construction & Versatile Turbo OptionsTo endure extreme exhaust gas temperatures (EGTs) without fracturing, this manifold and Up-pipe assembly are constructed from your choice of high-grade SS316 or SS321 stainless steel, assembled with flawless high-quality TIG weldings. The system anchors to the engine via ultra-thick, precision CNC-machined billet head flanges that prevent warping under intense thermal stress. To match your exact power goals, the assembly can be configured with 42mm or 48mm heavy-wall piping and features flexible outlet choices supporting universal T-Flanges or modern V-Band connections for your turbocharger, combined with custom V-Band options for your external wastegate.

Advanced Feature Set

Equal Length Runners: Precision-bent individual pipes designed for uniform Boxer exhaust flow dynamics and maximum turbocharger efficiency.
Integrated High-Flow Up-pipe: Included matching heavy-wall Up-pipe optimized for high velocity and unrestricted exhaust flow to the turbine.
Custom External V-Band Options: Integrated high-flow wastegate runner on the Up-pipe with precision V-Band flange options tailored to match your specific external wastegate size and model perfectly.

IMPORTANT NOTICE: V-BAND MEASUREMENT & FITMENT REQUIREMENT

Because aftermarket turbochargers and external wastegates vary significantly across different manufacturers, clients are strictly required to measure their V-Band flanges accurately.

Please include your car brand and model (Subaru WRX/STI), your turbo/wastegate brand and model, along with your exact V-Band measurements, in the checkout notes/info when completing your order. Providing these precise details and dimensions is the ONLY way to guarantee perfect fitment for your specific setup.

Production time for this part is 3-4 weeks since the order is confirmed!
