Got around to fabricating up the Weapons R muffler install and before I start lets just say it's a pile off work but I did enjoy doing it. It takes an enormous amount of time measuring for an exact fit, trying it on the bike then adjusting and trying again. Second time would be easier because I now have a copy. If someone can let me know how to post video I have a couple with the bike running with and without the db killers.
So here is the muffler I'll be using. It made from stainless steel and has removable muffler. It's available in a slanted tip or straight tip. The body is 4" in diameter so it fits nicely.
The first thing I did was to remove the mounting bracket off the top so I could position the muffler to the dimensions I needed and then welded it back on. I then cut the hanger off the stock muffler then welded it on the new one. In the photo below you can see the angle I used so that it would flow better with the bike lines. If you look at your stock exhaust from underneath you can see it's wider at the front.
I painted the welds with high heat paint to prevent them from rusting. I wasn't using stainless wire in the mig. You can see how the muffler is mounted using the Yamaha mounting method.
"Y" pipe bent using a exhaust bending machine. Sorry for the poor pictures but I was using my Iphone while I was working.
Mounted on the bike.
So here is the finished install.

"Y" pipe, it looks close but it's not.

I not sure how to post video directly to the forum but I'll give the links. I someone could help me with that.
The first video is with the DB killers in.

The second video is with DB killers out. The exhaust is deeper at idle and louder when revved.

Let me know how it compares to the "purchased" offerings. I have to say it was a pile of work and I would rate it a 9 out of 10 for difficultly but it was fun to do.
