All BC Fabs exhaust systems are designed and built in house in the UK by championship winning motorsport professionals.
All noise readings are taken at the recommended 0.5m at a 45 degree angle.
Designed and engineered by motorsport professionals, our Porsche 718 GT4 exhaust range unleashes the incredible flat 6 4.0l exhaust tone these cars are really missing. Removal of the OEM exhaust is a few nuts and bolts and the BC Fabs exhaust simply bolts up onto the existing OPF/GPF flange. This exhaust instantly increases the efficiency of gas flow which results in more torque, more horsepower and of course MORE NOISE. Shaving almost 50% of the weight off the OEM silencer this simple modification instantly engages your senses and further enhances the characteristics of the car.
Our Porsche 718 GT4 Race exhaust is for those who are looking to achieve as much noise as possible with only changing the rear box of the car. This design removes the use of valves and silencers which results in an exhaust which pops and bangs from start up. This is the simplest most cost effective solution to increase noise. This design merges right before the tailpipe to reduce resonance through the pipe within the low RPM range. Gasses pass through both the larger and smaller diameter pipes. Our calculated x piece amplifies the Porsche flat 6 tone as gasses on both sides of the engine mix revealing an incredible howl out the rear of the car.
Which Material is for you ?
With almost 30 years combined experience working with materials such as Stainless Steel, Inconel and Titanium within the most demanding areas of motorsport, we’ve brought top flight racing engineering techniques and a wealth of knowledge to the Porsche 718 GT4 exhaust market.
We offer our Porsche 718 GT4 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.
Our Stainless Steel exhausts offer a deep and aggressive tone.
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 than both Stainless Steel and Titanium which allows us to decrease the wall thickness of your exhaust, saving weight without compromising on strength.
Inconel offers a higher pitch in the higher RPM.
