Akrapovic Evolution header set (Titanium). Porsche 911 (991.2) GT3 RS 2020
Code: E-PO/T/4
Evolution header set (Titanium).

akrapovic

Fits:
Porsche 911 (991.2) GT3 RS 2020

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.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.

akrapovic

Fits:
Porsche 911 (991.2) GT3 RS

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.

Titanium is a highly corrosion-resistant material, which is particularly important in exhaust systems due to the exposure to extreme heat and moisture. The corrosion resistance of titanium bolts ensures longevity and reduces the risk of premature failure, ultimately saving the owner from costly repairs.

Sport Headers.

fabspeed

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.

The component is perfectly interchangeable with the original components, following the instructions in the constructor's workshop manual

RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector

REDUCED CELL CATALYTIC CONVERTER - 300 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still cutting pollutant emissions and boosts power and sound

ECU REMAPPING - ENGINE LIGHT
Replacement or removal of components such as catalytic converters, GPFs and electric actuators may cause the engine warning light to come on. In this case, the installer must reprogram the software to eliminate the light

END TIPS DESIGN - OE
The muffler must be used in conjunction with the original exhaust end tips

MATERIAL - AISI 304 STAINLESS STEEL
A choice stainless steel ideal for aggressive environments where combustion emissions can cause serious chemical corrosion on other types of metal

MAIN PIPE DIMENSION - 80mm
This is the diameter of the main pipe of the exhaust system

Please note: sports catalytic converters or bypass pipes do have type approval and may not be legally installed on vehicles manufactured after 1st March 2001. They can not be used on a public road and are not MOT compliant, they are designed for race and track cars only.
