I've been seeing this ad on EBay for a few weeks now. Guess they have a boatload of these exhaust systems at their disposal.

Does anyone know anything about the Jetson Exhaust that is being marketed here?

I realize it's cheap, like in under $100 for product and shipping.

Might this be a low-cost alternative?

 

If I was a betting man, I'd guess Chinese knock off of the old KLX250/KLX300 Supertrapp design. No reason it wouldn't work except again, the header is the big performance win and this is just the mid pipe and muffler.

 

Those wont fit our head pipe or will they?
