Performance Without Compromise: The GMC Racing Lineup

Don't settle for a simple collector. Choose artisanal excellence.

WELDING EXCELLENCE

Thanks to the expert hands of our specialized welding team, who pay meticulous attention to detail, GMC manifolds feature a unique type of welding, impossible to find in other products on the market. Precise, clean, and perfect, they give the product a flawless appearance, free from impurities and burrs, both inside and out. Furthermore, this welding positively impacts our product's performance, ensuring a much higher flow rate due to the absence of joints and residue from imprecise welding that joins components roughly. This allows the manifold to function optimally, ensuring the flow is not slowed or diverted in any way.

THE 4 IN 1 SYSTEM

Our 4-in-1 manifolds are designed so that the flows are parallel, preventing them from conflicting. This allows the product to guarantee maximum performance and minimize the backpressure and operating temperatures that would otherwise occur with a standard manifold. This system was born from the experience of our racing team, which has conducted years of testing and studies on the track and dyno. The system guarantees a power increase of around 10-15 horsepower and a reduction in operating temperatures.

FLANGES AND TEMPERATURE PROBE CONNECTION

All our manifolds come with an EGT temperature probe connection with a thread of your choice.

Each manifold is equipped with flanges, both the turbine side and the head side being made of stainless steel. They also feature a pipe connection system that ensures maximum product resistance.

4 IN 1 AND FLANGE MACHINED FROM BLOCK

The 4-in-1 solution machined from solid material guarantees greater reliability and better flow of exhaust gases towards the turbine due to the lack of joints between one component and another.
