Actually most of it was the original piping cut, welded, sanded, and painted w extream temp paint. The rear header normally goes down through the swing arm. I took that pipe and had it come straight out to the left muffler. Then I had the front pipe come up through. The opening the rear pipe used before.

Also did some cutting with the plastic under the seat. Fabricated a new undertail/heatshield and mounted the mufflers. To make a long story short.

Ps, R1 pipes are titanium. What a pain in the @$$. They can be welded, but its way to expensive. Much cheaper to simply cut and clamp.

 

Is there some sort of balance pipe between the headers? The front looks a lot longer than the rear. How does the bike go? It would seem to me that the rear cylinder will run pretty hot and the gas flows would be disrupted due to the loss of the pulse scavenging.

 

actually, ive had zero problems with the difference in the pipes. maybe bc theres very little back pressure, maybe just bc. i asked alot of the same questions to my mechanic before we started. in the end,i just know it workrd better than i expected.

 

Do you have dyno numbers from before and after?
