Full Version: Cobra Exhaust Pipe Size
I have a Cobra pipe coming for my ATC 70.My 70 has a 125 Lifan installed so the pipe will have to be modified.Would like to know the O.D. of the header pipe before comes.That way I can have some pipe on hand.

Stock pipe will work fine, so I dont see why the cobra wont work. Dont forget the cobra takes two (2) exhaust donuts

So tha stock atc70 pipe will fit onto the lifan 125 semi auto motor then? Any mods needed?
To the OP how did the cobra fit? how does it sound? very loud?
