Okay i want to make a straight pipe for my warrior, what size tubing will i need, i dont have a manual to look it up but does anyone know what size il need? thanks

 

just measure the headpipe or your existing stock muffler, ive seen some people take the oem muffler and gut it out and put a custom welded end cap and painted black and was pretty decent, a straight through pipe honestly is gonna take a mean toll on your bike overtime, very low or no backpressure really strains the engine.

 

ya but i dont have the muffler with its 40 minutes away at my summer home thats why i was wondering if anyone knew the measurements

 

1.5" OD. Bad idea running a straight pipe,bad for the bike,bad for the neighbours.
