Are the pipes the same across models?

[Buster-boy]

I have an 82 GS450LZ (model X, if that matters). I know the 80-82 models are pretty much the same.

I need new exhaust pipes. I look at the parts fiche and I see there are two styles for this model. One looks like a three piece setup (top illustration on the fiche) the other a two piece setup (bottom illustration on the fiche). I have the one on the bottom - the two piece.

When I look at the other models on the fiche (GS450E, G, T, etc) the pipes all look the same, they just have different part numbers.

What I want to know is, and I hope someone can tell me, which ones will fit my bike? Will they all fit? Will only some of them fit? Are they the same pipes just different part numbers for the different models?

Also, I know MAC makes a 2-1 for this, but they're $269 and that's more than I want to invest at this time.

Thanks and I appreciate anything anyone has to offer. Oh, and if anyone has any for sale I might be interested in taking them off your hands.

Thanks

Jim

Big difference will be the length as the "L" mufflers are shorter
