The B58 is a special engine, transforming from the N54, then the N55 and now to the B58, only true tuners and car enthusiasts know the power and potential the B58 carries. With that, we thought, there should be one of the highest quality exhausts one can purchase to withstand all that power, boost and heat. That's why we created our F3X B58 Valved Catback system. This system utilizes our own valves to open and close the valves via a remote and receiver provided to you in the kit. This gives users the flexibility to open and close the valves on demand, whether in sport+ or in comfort. Our titanium system provides a unique tone which is like no other, much like our MK5 B58 Supra system. Our system features one small resonator installed in the midpipe to help drone out the rasp these engines produce and help create a deeper, clean tone. Titanium will help sustain the heat and closing the valves will provide adequate back pressure when needed. If your looking for an exhaust which gives you the best of both worlds, loud and obnoxious with the valves open, but a sleeper and safe from cops with the valves closed, this is the exhaust system for you.
