Mandrel Bending is performed using our state-of-the-art CNC Mandrel Bending Machines, a Mandrel a solid shaft with balls that is slightly smaller than the tube inserted to prevent the tube collapsing during the bend by giving internal support, ensuring a consistent internal diameter without deformities to the outside diameter.
Uses include Water pipes, Intercooler pipes, Exhaust Systems.

Exhaust Silencer
Exhaust Silencers reduce noise emissions, the pressure wave is created by high and low alternating pulses.
Can a silencer increase performance?
An enhanced silencer can decrease resistance creating a louder more powerful engine sound, this reduces backpressure increasing gas flow and improving engine performance.

Our exhaust silencers can be tailored for optimum results specified we also offer a repackable version on some.

Combining multiple exhaust pipes into one through various combinations tailored to the engine’s requirements, Merge collectors are important for increasing an engines torque and BHP by combining high flow and velocity,
Variants range from 2 into 1 to 5 into 1 and different diameters, designed to be integrated by clamping, welding or V Bands.

Catalytic Convertor
Catalytic Convertors convert emissions reducing the number of pollutants expelled through the exhaust system, they contain a ceramic monolith, the exhaust gases flow through the monolith reducing the pollutants.
These can be fitted to the exhaust system through welding, clamping or V Bands.
Photo shows one of our Catalytic Convertors with welded on cones for self fitting.
Purge Welding

Purge Welding
Purge Welding
Purge welding removes oxygen other gases from the welding site to prevent oxidation and contamination, creating a higher quality weld that is stronger and has a lower porosity making the weld less prone to cracking or failing.
Photo shows two of our silencers built by ourselves at JR Race Exhausts, the welded on V-Bands show an example of a purge welding.

V-Band Clamps
V-Band Clamps are also known as V-Band Flanges these are two mating flanges connected by a V Shaped Clamp designed to be welded onto the joining parts.
V-Bands allow for ease of changing parts for different applications, on a exhaust system.
Photo shows V-Bands on an exhaust system that has been designed and fitted by ourselves at JR Race Exhausts.
