Bicylce-Engines expansion chamber

Why did you make 2 threads that are exactly the same? I thought they were the same thread and thought that my comment didn't show up lol. Well, might as well copy paste my comment here so everyone can see it: That expansion chamber looks really tiny, hardly even worthy of being called an expansion chamber lol. Anyways, I doubt you will see much improvement with one that small, but since you already have it, you might as well put it on and see what happens.

I'd recommend a pipe that goes down.

LoL, I did an over the top, diy exhaust pipe once. Once. Ended up with a "breather hole" in my brandy new Carhartt winter bib overalls due to (looked cool) heat guard.
But that was my bad as to design.

This don't look any friendlier to your

inner thigh than the last pipe...

I like the SBP X-chamber, you can adjust the turning and the routing...

... and you can do some really creative things after the pipe to quiet it down if you want to get creative...

That extra exhaust pipe is an auto 'glass pack' muffler welded on the end and plenty far back enough to not be a be a 'thigh burner'.
That bike really sounded cool ;-}

My mistake I thought the OP was in reference to proper expansion chambers and tuning, not pipe location.

Seems like spreading your legs a bit could avoid this burning problem I keep hearing about.

Here is a good example of what people think is a pipe that will burn the **** out of you but since its quite far back from the engine it hasn't burn my wifes leg at all. I believe this topic is subjective to the person and their abilities to stay aware.

Also avoid wearing shorts if burns seem to be a frequent problem...

Hey KC, scooterruder1 here. I just saw you personal bike exhaust set up. Something like that would be perfect on my mountain bike. I'm not sure if that pipe is made for the extra heat that my engine would generate, but I admit I don't know much when it comes to mechanics. Not sure if you'd be willing to do a custom exhaust at this time, but that would be cool. Thanks!

I saw this review response on sickbikeparts about a complaint with the SBP----SBP response:
After working directly with the customer to evaluate the cause of his issue we determined it to be somewhat of an extreme case. The addition of a high compression head, reed assembly, carburetor and ignition upgrades all contributed to higher than normal exhaust temperatures. In reality only the seals at the exhaust header saw any serious degradation. Again, this is not typical.
