    Huge fan, big gain in response and sounds great

    bought it early last year, had to wait a couple months based on supply of certain components no blame to them the world went down a crap shoot. when i installed it was very surprised at the quality of not only of the product but the packaging and how easy it went on, once it was installed it gave the throaty sound i was looking for and the throttle response and still looks great after being dropped and loads of heat cycles, the coloring of the ti and the pops on decel was just the cherry on top
