Mandrel Bends formed to provide the smoothest gas flow exit, superior to many existing designs.

Our Y-Pipe in twin 3" merges beautifully with Mandrel Bends into 3.5" Centre, providing the smoothest gas flow.

This exhaust is used throughout out tuning packages but is available on its own at a RRP of £1600, please contact us for member discounts and special offers!

UPDATE: We have now tweaked the design of the rear silencers to remove even more cabin noise, still with the same signature noise and tone outside of the car and under throttle, yet a few db quieter at idle and cruise for a more enjoyable driving experience.
We are well aware that a loud and poorly silenced system will sound great... initially. Yet can be tiring to own, especially on journeys. The key is to design the system to give the noise and tone of the GTR that we all love, yet keeping the cabin noise to a minimum and removing the drone that even a simple y-pipe can bring.

A few more images of the latest rear section design with a few subtle tweaks to the silencer design to refine the note and tone of the system. Retaining the trademark GTR sound yet reducing cabin noise, quieter idle and cruise, same characteristic GTR howl under load!

Note, this is just the rear section, the system comes complete with the centre section AND y-pipe section as shown in the pictures in the previous post.

Note, the smooth flowed design through the rear silencer sections and the outlets. This is a 3.5" centre section which splits to 2x3" pipework through the silencers which will cater for 850+hp without any restriction.
