Has anyone ever used conduit for an exhaust pipe, I was thinking of connecting it to where the muffler broke off of the exhaust pipe good making my muffler in a tent at the rear of the bike below the sprocket on the left
 
seen a lot of folks do that just to move dripping to rear - with metal or hi-temp rubber hose
 
The exhaust on a 2 stroke is very important to how well the motor runs. Just adding pipe is not going to make it run well or can make it run worse. Do some research on 2 cycle exhaust. Good luck.
 
Actually my experiments proved that extending the header of the stock pipe by 6" improves low speed power. But I used the same diameter steel pipe and had it welded.
 
conduit works, welding galvanized is a nightmare though. you gotta grind the zinc off or it won't weld right and will give you a bad case of zinc shakes

I agree but if you do not have a good expansion chamber it is not going to run any where near potential. A good pipe is the number one best upgrade you can do on a 2 cycle.

I have to disagree, my best upgrade for a HT engine is porting and matching

I have done both the expansion chamber and porting.... Porting worked better for me
 
Used both combined, don't see much of a power increase with the expansion chamber on....
At very high RPMs it has better power but it's up so high you can't do anything with it, probably just my expansion chamber
