New Pipes GS 450 L '81 Help

[boston]

I'm looking to put on a new set of pipes on this GS 450 L... the original ones are cracked and worse for wear. I'd like to put strait pipe on there and was wondering if there are any recommendations or things to worry about in the process. This is my first work done to an older bike and I don't want to put anything on there that could affect the carbs negatively...

any good places resources for finding strait pipe?

My exhaust was damaged as well. I bought my pieces from here

They market it towards yamaha xs owners, but the only thing about it for the yamaha would be the flanges and collars. I work next to a machine shop so i just machined down the flanges and they ended up fitting my GS like a glove. I then cut and welded myself a simple set of pipes. I also bought some shorty mufflers from that site as well to save on shipping. Here is a picture of it.

Also, Like cowboy said, you'll want to up your jet sizes. I think I have 20's in mine, and there are tons of other postings about jet sizes.
