exhaust header

I am in need of a 26mm exhaust header for a 1978 sachs, 49cc engine. It exits on the left side of the bike. My original exhaust was a 21mm but I put on a larger carb and need the larger exhaust pipe now. I only need the exhaust header pipe because i believe I can reuse the existing muffler can't I?

is the muffler 26mm or 21mm? im not sure how much the header will help with the stock muffler...doubt it will fit either.

Re: exhaust header

the muffler is 26mm. what sachs did was install a restricted pipe on the 20mph bikes. it is 26mm inlet where it attaches the the cylinder and then it is narrowed down to a 21mm pipe that is bent out and back and just before it goes into the muffler it is increased back to 26mm. I am assuming that is the only restriction in the exhaust between a 20mph model and a 30mph model. I was thinking the 30mph models were more common than the 20 mph models but have no idea really.
