Direct replacement for the restrictive OEM headers, offering improved power and throttle response throughout the RPM range.
Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade material you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
FEATURES:
• Fits all Porsche 991.2 GT3 / GT3 RS vehicles 2017+
• Includes German-imported HJS 200-Cell Tri-Metallic Sportcats
• Saves 2 lbs from the rear of the vehicle
• CNC mandrel-bent 1pc primary header tubes
• High-velocity motorsports-style merge collector
• Constructed from T304 Stainless Steel
• All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty
DISCLAIMER: Fabspeed's 200-cell high-flow catalytic converters are not C.A.R.B. certified and are for Off-Road Use ONLY in the state of California
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

Evolution Header Set converts the slip-on system into a full system designed to give noticeably increased power at higher revs. Handcrafted titanium headers incorporate 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Header Set utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, it delivers a sportier and hard-hitting sound, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance.
When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.

Evolution Race Header Set converts the slip-on system into a full system, built for the track and gives the Porsche GT3 the extra performance to match. Handcrafted titanium headers incorporate 100 cpsi sports catalytic convertors and titanium flanges—cast in Akrapovič's own foundry. The system offers a perfect power curve right from 3,000 rpm to the very top of the power band, designed to continually increase performance as the revs rise. Along with improved torque and the maximum weight savings to enhance handling, adding the Evolution Race Header (Set) will have the car performing like a true cup racer—with a deep, loud, and powerful Akrapovič racing sound to match its performance.
