ALL THE PERFORMANCE WITH OR WITHOUT THE NOISE!

Give YOUR Kia Stinger the sound you want, and the performance to go with it!

MACH 2 TWIN VALVE KIT
With its single venting outlet, the Mach 2 is configured from the factory for full recirculation venting for the performance-minded driver who just wants the benefits without the sound. Of course, should the temptation to make some noise arise, it is possible to vent the Mach 2 valves to the atmosphere for a blow-off sound with the separate purchase of an atmosphere venting kit.

With over 20 years in the business of designing and manufacturing bypass and blow-off valves, GFB have learned a thing or two about managing boosted air, as well as the difference between a good blow-off valve, and a great one! Quality and performance are built into all GFB valves, so regardless of which of our kits you purchase, your investment will last a lifetime (which is why these products are backed by a lifetime warranty) and offer the best possible throttle response and boost holding that any bypass or blow-off valve could deliver.

Our range of bolt on kits for the Stinger offer many different options when it comes to venting sound, from silent to extremely loud, and anywhere in between. Because the Stinger does not use a MAF sensor, you can vent your BOVs to atmosphere without drivability issues such as backfiring or stalling.

Unbeatable quality, direct bolt-on fit, exclusive venting bias adjustment to control the sound, lifetime warranty, AND a performance benefit – that’s what we mean by Performance Without Compromise.
