Exhaust for GXH50

Ok, so I've been searching and searching for exhaust solutions for the GXH50. Does anyone make a different pipe for this thing than the stock box? Or are small engine exhaust ports basically all the same and no matter what I buy will work. I don't really want the little guy blowing his exhaust all over me every time I ride. Someone must have come up with a solution for this I just know it..

As always, thanks for any help you guys can provide.

Thanks for the reply, the GXH50 is the Honda 49cc 4 stroke. I think I may be going with a pocket bike engine though which have quite a few options for exhaust and everything else for that matter..
