anyone use the x port exhaust headers?

is the so-called "header effect" of lowering the power band actually noticeable in the real world?

or is it a "boost bottle" and "racing carb" kind of thing.
im running a factory exhaust, if that matters.


as always, much appreciated.

Definitely! I got a SBP expansion chamber pipe and immediately noticed a huge increase in performance. I'm using a pretty long header (about 16"-17") and my low end is great. I'm up to 25mph in about 2 seconds now.

No, I'm not using those headers and don't know about them.

several of the sponsors here sell these, and make some pretty big claims... and no one has ever even heard of them?

i'll take that as a bad sign...

I have seen them previously. Theoretically it should work. You want the exhaust going in the straightest path you can before any curves. Brown has one on his bike. I like it, but wouldn't spend the money on it.
