THE BC FABS PORSCHE 718 GT4 / SPYDER / GTS 4.0 MANIFOLDS & UNDER AXLE PIPE OPF DELETE
The BCFabs Porsche Manifolds & Under Axle OPF Delete removes the highly restrictive stock manifolds, 600 cell cat and the OPF. In turn replacing them with BCFabs equal length primaries and HJS Motorsport 200 cell sports CAT. Every part of this custom-built Porsche exhaust has been meticulously designed to optimise power, torque and sound, bringing these cars to life. The BCFabs Manifolds & Under Axle OPF Delete increases the efficiency of exhaust gasses resulting in a true GT RSR Porsche sound that is a truly fantastic upgrade to experience.
Offering optimum power and torque, the BCFabs design is positioned under the driveshaft as opposed to the original Porsche route of up into the wheel arch and over the driveshaft. This optimised positioning also helps to reduce temperatures within the wheel arch. The OPF Delete / Under Axle Pipe then joins back up to the original position where the stock Porsche rear box is mounted.
This Porsche exhaust upgrade is suitable to use alongside the existing Porsche OEM back box or upgrade to the BCFabs custom-built rear pipe for ultimate performance and sound.
We recommend using the BCFabs rear pipe to extract the full power and sound.
This alteration can be reversed at any time, leaving no memory of the upgrade.
Which Material is suitable for a Porsche 718 GT4 / SPYDER / GTS 4.0?
With over 30 years’ combined experience working with materials like Stainless Steel, Titanium, and Inconel in the motorsport industry we bring knowledge and top-flight racing engineering expertise to the Porsche 718 GT4 / SPYDER / GTS 4.0 exhaust industry.
Porsche 718 GT4 / SPYDER / GTS 4.0 Exhaust in Stainless Steel
Our Stainless Steel exhausts offer a deep and aggressive tone.
We offer our Porsche 718 GT4 / SPYDER / GTS 4.0 exhaust systems in 304 Stainless Steel which can withstand high heat cycles and long term vibrations unlike lighter materials such as Titanium which tend to crack over time.
Porsche 718 GT4 / SPYDER / GTS 4.0 Exhaust in Inconel
Inconel offers a higher pitch tone in the higher RPM.
Superior when it comes to exhausts! Inconel is popular in high end motorsport such as Formula 1, rallying and endurance racing, where strength, weight and heat defence is paramount. With it’s high nickel content, Inconel is stronger and is resistant to corrosion when compared to both Stainless Steel and Titanium which allows us to decrease the wall thickness of your exhaust, saving weight without compromising on strength.
Prices are plus VAT where applicable.
We try to hold stock of all Porsche systems but due to popularity it may take up to 6 weeks for shipping in some cases.
