The BCS Valveless Turbo back (with 125mm road-legal 100/200 cell cat) WRC exhaust is our loudest option for the VW Golf GTi Mk5 2.0 TFSi, providing you with the maximum possible full-time audible thrill from your GTi.
The system has a greater audible volume than the cat back offering, however, with careful design and development we have created a system that ensures that any unwanted in-car frequencies are removed, leaving you with a perfect drone-free experience, together with our characterful pop and burble, free-revving sound.
The primary use for the WRC variant system is the track or closed/private road.
As with virtually all of the TFSi engined vehicles, there is very little performance gain to be had from the cat-back system on its own, due to the incredibly restrictive downpipe and twin OEM cats. However, by opting for our unique down pipe and high flow cat the power potential will massively increase, firstly with an initial 22bhp kinetic, and then once mapped all the way up to a stage 3 the following figures are achievable (along with suitable additional hardware...)
The TFSi K03-based AXX BWA performance guide
- Stage 2 custom remap 275 hp 330 lbft
- Stage 2+ custom remap 290 hp 360 lbft
- Stage 3 k04 0r k03 hybrid custom remap 350 hp 370 lbft
The TFSi K04-based BYD BWJ BHZ CDL Performance guide
- Stage 2 custom remap 340 hp 340 lbft
- Stage 2+ custom remap 380 hp 400 lbft
- Stage 3 k04 0r k03 hybrid custom remap 550 hp 550 lbft
(all Performance figures are based on levels achieved by R-Tech Performance)
If you require more power from your GTi we recommend the 76mm (up to 400 bhp) or 90mm (400 bhp+) downpipe to go with this system.
We also recommend that the Powerflex up-rated dog-bone mount is selected when purchasing the full turbo-back system. This will decrease the amount of stress on your downpipe once the car's torque has been increased after re-mapping.
The trim options for this product are

As the original rubber mount for the centre silencer is prone to wear in regards to its ability to support and prevent excessive movement, we recommend its replacement with the upgraded VW rubber as shown below.
