M's Single Velocity Stack Mean A$$ Sound From the Throttle Video.

[NA1/2-R GT]

Very high quality construction (Made in Japan of course)
Sounds very intoxicating. If I were to use it on a quieter exhaust, more sound can be heard from the throttle body.

I like the part when he fingers the rim and says "Nice. That's nice velocity right there."

LOL.

So there is no air filter between the engine and the intake?
