so wieght savings was part of my goal when i did this and yes it easy drops 10-15 lbs between the two cans. My other goal was to go to a 2 into 1 setup and use the other can as a storage box which now holds my elec pump, a front and rear tube, first aid, spare plug, zip tyes and jb weld.
So was it some work, yes, does my bike look stock w/ addtioanl storage and more rumble, yes. are the cans much cooler, yes. Did it affect performance and or mileage, no.
I looked at it this way if it all worked it cost me a few bucks for material and some time which i was willing to put into it. If it did'nt work, well then i buy after market cans which i was going to do. And now i dont have to.
