I have a silencer for my tanabe racing medallion, it was hella quiet with it in, like i could hardly hear my exhaust at all, and with it out it is LOUD as HELL. then i went to the dyno, and while on it, decided to test, with the silencer, i lost exactly 21 horses to the wheels!!! so in a fit, I threw away the silencer for making me lose so much horsepower. I didnt really care, then on my 12 hour highway trip to Panama... the loud wwwwaaaaaaaaaaaaaaaahhh of my exhaust got pretty damn old, and actually wished I still had the silencer....

okay, im done going of on my own tangent now....
