Each cylinder sees a true, matched primary length that times pressure waves at the collector for strong scavenging, quicker cylinder emptying, and a broader, cleaner power band.

Crafted specifically for the 992 generation GT3 and GT3RS models, this component ensures a perfect fit and seamless integration with your factory exhaust system. Engineered from high-grade materials, the header offers durability while reducing weight for better handling. Its advanced design improves throttle response and horsepower, making it an essential upgrade for enthusiasts seeking uncompromised track and street performance without sacrificing reliability.\u003c\/p\u003e\n\u003ch3\u003eAdvanced VANTA Coating for Heat Management\u003c\/h3\u003e\n\u003cp\u003eFeaturing the innovative VANTA coating, this long-tube header effectively manages extreme temperatures generated during spirited driving. The black VANTA finish not only provides a sleek, aggressive look but also acts as a thermal barrier to reduce heat soak into the engine bay. This thermal control helps maintain optimal engine temperatures, protecting sensitive components and enhancing overall efficiency. The coating also improves corrosion resistance, ensuring that your Porsche 992 GT3 long-tube header remains in prime condition under rigorous use, whether on the track or daily driving.\u003c\/p\u003e\n\u003ch3\u003eEnhanced Exhaust Sound and Performance Gains\u003c\/h3\u003e\n\u003cp\u003eInstalling the Yonristic VANTA competition long-tube header on your Porsche 992 GT3 significantly enriches the exhaust note with a deeper, more aggressive tone. This upgrade unlocks hidden performance potential by optimizing exhaust scavenging, which increases horsepower and torque across the rev range. Drivers will notice improved acceleration and throttle response alongside weight reduction compared to stock headers. Designed for both street and competition use, this long-tube header delivers measurable gains and an exhilarating driving experience, making it a must-have for passionate GT3 owners aiming to elevate their car's performance and sound quality.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Yonristic Performance","offers":[{"title":"Free Flow (Race Edition)","offer_id":48522721624288,"sku":"YR-4122-POR-FRE","price":2499.0,"currency_code":"USD","in_stock":true},{"title":"200 Cells Catted (Street Edition)","offer_id":48522721657056,"sku":"YR-1065-POR-200","price":2999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1003\/2430\/files\/992GT3LongtubeHeader.jpg?v=1767897327","url":"https:\/\/www.edoperformance.com\/products\/porsche-992-gt3-gt3rs-competition-long-tube-header-vanta-yonristic-performance","provider":"EDO Performance","version":"1.0","type":"link"}
