OK so as the riding season is going to be tapering off over the next couple of months i am beginning to plan some upgrades for the off season. my plan is to have a y pipe fabed up and put in place of the goat bladder. my question is if i do this and completely remove the goat will it make latter exhaust swaps more difficult or do most aftermarket setups bypass it any way?
The aftermarket exhausts all require you to remove the goat bladder, and most of them come with a bracket to relocate the rectifier to the spot the goat bladder was.
Can someone post a picture of the goat bladder installed on a Drifter?
Here's a shot from when I had the bevel drive off. Not real complicated
There's just something unnerving about the goat bladder. Reminds me of those weird creatures on the Matrix.
That pic doesn't help me at all. What is a goat bladder?

It looks like a cat converter and sits under the bike... its big and obvious if you have the stock pipes.

It's about the size of 2 grapefruits sitting next to each other. The front and rear cylinder pipes enter it on the right side, and the stock muffler exits from a larger connection on the same side. The one on the Nomad has 4 pipes, all the same size, 3 on the right (2 in, 1 out) and one on the left for the left side muffler. In some applications, ti has a catalytic converter function, but it's really just a large expansion chamber/collector to increase exhaust volume without increasing noise volume. It works in conjunction with the restricted intake system to quiet the exhaust note. Since I recreated my airbox to remove restrictions, the exhaust has gotten MUCH louder than it was. The same thing happened when I reworked the intake on my "W"...no change to the mufflers, but the sound volume increased by quite a bit. When I got my stock exhaust for the Drifter (I actually had to get 2 complete systems to get perfect parts), I took a good look at each system. I believe I posted the pictures I took here, somewhere. The goat bladder...indeed both of them I have is an empty shell with 2 perforated tubes coming in from the engine pipe spigots, extending about 4" into the shell. They are completely perforated around the outside and in the ends. The outlet spigot to the muffler is not restricted in any way. You could put the head of a cutting torch inside the shell and burn off the tubes, if you wanted. There is a shield on the left side of the shell that is probably there to help with heat build up on that side to protect the Regulator/rectifier that is normally mounted near it. The muffler, itself has a single LARGE tube running into it, where it splits into 2 unrestricted tubes running the length of the muffler. There are NO BAFFLES...neither muffler showed any signs of molestation, and were identical inside. The tubes in the muffler are perforated as well as being a straight shot from the inlet to the outside world...
