    NOS 250sx Supertrapp exhaust

    This is the exact kit I installed back in 87 on my SX, and that's still on it today. It aint cheap, but you don't see these popping up much anymore.

    Shoot, I wish I had some extra cash. I would buy it just to put on a shelf in case I need one down the road.

    Yeah, there is actually a pretty big difference between my SX with the supertrapp vs my SX without.

    How loud is the Supertrapp compared to stock? I know my buddy back in the day had an XR350 and it was loud, even after adjusting the disks.

    I don't want to be a donkey here, but I've gotta chime in. Have you raced a stock SX? I used to run a supertrapp and I was SURE it had more nuts. Turns out, it was all in my mind. "Loud" and "Fast" are not synonyms. Try riding it with earmuffs on. And please don't think I'm being a smartass. I know that you know your stuff Shortline, and I respect your opinion. I'm just saying that I was fooled. I wonder if its possible that you have been also. Honestly, I would like to know.

    Definitely a difference in mid range power and it's obviously louder than the stock exhaust but it's not excessively loud .
