    I wanted to say Bassani too- but Im no expert so I was cautious to say so. 1st.-
    Looks like its for a 200X though (exits outside the frame-not thru center). BUT will still work if so..
    ...I had one that exited thru the center for my 185s

    Will it fit a 185s with rear fenders?

    Looks like a 185s/200 pipe to me. It will run through the center of the frame.

    It should still clear the fender if it IS for a 200X. BUT-After a 2nd look, Im not sure it IS for a 200X because of the rear mount location/position.
    I assumed it WAS for a 200X because I dont see the megaphone section angled as I remember it being on my 185s (centermount). Sorry for the confusion....Someone on here that knows better than me Im sure will clear this up for you soon. ...(remove foot from mouth)

    Well i just bought it for my 185s project. So were thinking its a bassani that will come through the center like stock? The seller on ebay had it listed as oem but that cant be right? Any ideas what jetting ill need with this pipe and a uni filter? Will this exhaust add hp?

    Kinda looks like a 200s piece., then again, most stock exhaust has a large round tube before the tip, so it could very well be aftermarket.
    Never forget the past , but dont dwell on it.

    Well truck, if it is an aftermarket exhaust and you use a uni filter and rejet, then it should add power to your trike. For a little more, you can drill some holes in your airbox lid to let more air in. How much power will you add by doing all of this? Not sure. Whatever you gain will feel like quite a bit since 185s didn't have a whole lot of power stock anyway. What size jets to use, altitude makes a difference. Even two machines set up exactly the same way can respond differently to the same jetting changes. While I don't have any numbers for you, at a wild guess, I'd try to go up 4 or 5 sizes on your main jet. You may have to go a little bigger on your pilot too. Try lowering the clip on your needle. You may have to get a different needle with a different taper on it. Jetting isn't an exact science, it's usually an experience in trial and error.

    It showed up today. It is the kind that goes in the center like stock. Its in good shape and has a way bigger headpipe than stock. When i put it on ill rejet a size or two up and move the needle one notch. So its sake to say its a bassani exhaust?
