Triumph Rocket 3R & GT 2500cc Stainless Steel Exhaust Manifold

Choose from Stainless Steel or Titanium 

Finally, there's an exhaust manifold/header that lives up to the power of the Triumph Rocket 3 2500.

We offer two material options either lightweight Ti1 Titanium or High-Nickel Stainless Steel. Each option significantly improves exhaust flow efficiency by creating a low-pressure area (mild venturi effect) as exhaust gases pass each cylinder exhaust port. This characteristic is essential for enhancing engine volumetric efficiency, something that the OEM 3-into-1 manifold cannot achieve. This simple bolt-on addition is perfect for performance enthusiasts who want to recover lost efficiency and eliminate all restrictions while also making a visual statement.

The VANDEMON Manifold/ Header can be used in conjunction with any of VANDEMON's three slip-on muffler options that use a single O2 sensor up to year 2023.

The surface finish of the Stainless Steel option is highly polished and needs minimal maintenance to maintain its appearance. This is due to the higher percentage of nickel used in our stainless steel compared to what is generally used in the industry. 

The surface finish of the Titanium option is a brushed natural finish, which, after one heat cycle, will change to a rich blue colour with red tinges and will never require polishing to maintain its appearance.

Carbon fibre covers are provided to protect against heat, complementing the exotic appearance.
