The ULTIMATE header system for the GT4RS is here! We took 30+ years of Porsche engineering experience and pulled out all the stops to design our RENNKRAFT™ Long Tube Header System. After analyzing the factory system we decided to move the primary catalytic converter to behind the rear axle. This gave us the room to create true long tube headers while also ditching the factory 700 cell ceramic catalytic converter in favor of an HJS 200 cell tri metallic sport catalytic converter. The combination of a long tube header design and sport catalytic converter DRASTICALLY improves power and sound. This is all WITHOUT triggering a CEL (Check Engine Light) thanks to our heavy metal loaded high quality HJS catalytic converter. We also integrated our RENNKRAFT™ system, which allows you to easily swap between cats and cat bypass by using the quick release v-band clamps (patented). So if you’re going to the track you can swap in cat-bypass pipes easily. The icing on the cake is our new bi-layer heat shielding that can withstand up to 2400F / 1300C and dramatically reduces radiant heat onto surrounding components like the rear shock body.
SOUND:
Unleash that GT3 derived powerplant on the world! These headers with sport cats turn the GT4 RS up to eleven. With the factory muffler still in place, you’ll be treated to an aggressive deep tone with the ability to turn the volume all the way down by turning off PSE (Porsche Sport Exhaust). Pair this system with our Valvetronic X-Pipe for an absolute ripping high pitched exhaust note while stilling having the ability to turn the volume down using the PSE button.
POWER:
The most powerful header system for the GT4 RS, period. Max gains of 48 WHP and 54 ft/lbs of TQ are seen at 4700 RPM. That’s 53 HP at the crank! Peak power goes from 456 to 490 at the wheels. You’re going to feel the power that this system adds to your GT4 RS!
