Top Secret, one of the best and most famous tuning workshops out of Japan are finishing up their titanium exhaust system with a difference for their R35 GT-R. In their warehouse sized workshop in Chiba just outside Tokyo they’ve come up with a something a few guys have been waiting for.

So the unique thing here is that there are two exits for exhaust gasses. Ordinarily the exhaust gas flows through the right hand side, out the muffler. This is relatively quiet (for a fat titanium exhaust that is). If you decide you need more noise or better flow you can open a butterfly valve to the second, no muffler exhaust outlet.
