Don't line up correctly how?
On the non-Breakout version, the gap between the pipes becomes smaller as you get closer to the end, and then the tips don't line up correctly. I thought this could be corrected by modifying the frame bracket, but I discovered that the front header pipe was too short for the mod to look right. So after kicking myself for not waiting, I pulled the new/old pipes off and installed the correct set. Also, while switching out the set I notice both header pipes are different, the front pipe being almost an 1 1/2" longer, along with a different frame bracket that allows you to tuck the pipes closer to the bike.
Maybe this isn't a big deal to most, but I have severe OCD and I wasn't about to ride a bike with crooked pipes...
