If cars like yours typically suffer issues such as backfiring and stalling when using a fixed-ratio atmosphere-venting BOV, the Respons can help. By adjusting the venting bias to suit the car you can achieve a blow-off sound without having to put up with the issues. Like all GFB valves, the Respons utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.Shipping Notes

Definitely stylish and true to fit
An amazing set fits perfectly. I would necessarily call it a track suit because it’s more stylish than that however, the comfort is track suit / walking suit feeling. I got mine in 2x and it fits as I expected it to so yes it is true to size. The colors don’t fade and the weight of the set feels like it was made with quality material, not some flimsy sown together item full of loose strings.
