search pipeless416 i think. he did duals on his

well u could make the ones by urself like pipeless did with his hmf's
or check out the lte duals (looney tuned exhaust)
This link shows the exhaust I counldnt find it on the LTE website but this has everything u need and it runs juz over 700$
U could make duals urself tho and it would b way cheaper just more work

Im a great fabricator and a welder so i planned on makin duals myself. I watched Pipeless's video on Youtube.com and say that he used a head pipe off a YFZ but didnt know what year... and If I figure out a cheap and easy yet good looking way to make them, im gonna offer to make dual for anyone for a cheap price or trads for 400EX parts.. I also fabed a bracket so my rear sub frame can now take any grab bar off a Yamaha because I had a sweet wide grab bar off a 1997 Warrior.

another question.... i checked out the site where the stainless duals are and they say you have to jet the carb and relocate the battery... where would you put the battery and what would i use for jets? I plan on swaping my carb with a 450r carb anyways... would that solve the jet proublem? and do I really need the stainless air box?

The stainless airbox would give u a place to relocate the battery thats why its in the kit
The aluminum airbox i have is from UM racing (got it for 20$ off a friend)
Its ok i like it because it gives it a cleaner look without the battery outside the box
Im not sure about the head pipes or jets in a 450r carb cause idk what your other mods r

i think the engine might be 10 over but thats prob about it. i havent had the wheeler for long to find out

well im still not real sure, jetting and jetting right is more or less a trial and error thing and it doesn't hurt to have extra jets

right... ill just buy some jets for the 450r and 400ex carbs... thanks for the info
