Great, but expensive!
... was looking to buy one, but $9,529.00 shipped then installation is a bit steep for just the sound with minor performance change. Also, I am curious what the impact of the closed exhaust valves will be on the motor (will the internal exhaust valves in the cylinder head get fouled and caked with carbon due to increased backpressure?)
