Our systems are manufactured from Inconel 625 .
This material is used for F1 systems and the Hypercars P1, 918 and La Ferrari.
 
The BRE X pipe system (Non Valved) transforms the orignal sound of the GT4RS and offers radical improvement to the new GT4RS / Spyder RS equipped with GPF / OPF.
A very popular choice for those looking for an all out race car sound whilst still keeping emission leglislation.
This system retains the stock emission related components including standard cats & GPF / OPF.
There is no requirement for ECU tune and no CEL light.
The exhaust is a simple bolt on bolt off fitment and compatible with stock tips.
 
Helm holtz resonators are installed to reduce/ minimise drone.
There will still be some audible increase over stock when cruising, but this is subjective person to person.
For the Non Valved system, the factory Porsche vacuum system is muted safely and fully reversible.
 
Please note, helmzholtz resonators will only come when purchased with BRE over axle pipes due to packaging constraints.
 
With the BRE rear setup only, no ECU tune is required and there is no CEL warning light.
Our system will fit standard tips.
