You are in California, I don't think you understand how loud it is. They are really loud. Is that what you want? Don't you guys have to be the quietest of all?
Don't be eager to buy, you could get it cheaper if you wait. He just wants to get rid of it and is putting the pressure on you.

what do you think it would do in the performance area for my bike? Anything.

This is a complete contradiction to the pipe, and the performance gains won't be much if any at all.
The YZ pipe is really loud also, you can get a Q2 for your bike, they look good and modern, will make an improvement, and are quiet. I hear that when you match it to a powerbomb header, it makes a nice improvement indeed, all being quiet.
I think you need to think about what you want and what you need. Stick to the stock pipe for now, The procircuit is seriously loud (as well as the YZ pipes) that is why that other bloke is getting rid of it for sure. I have one, but I don't have to worry about noise and no one will hear me anyway.
If you need to be quiet, stick to the stock pipe or Q2 if you want to spend some cash on the old girl.
I think you are better off getting a big bore kit for your bike, They are just as cheap if not cheaper than an exhaust system for you guy's and the performance gain far exceeds that of a pipe upgrade for sure. Your engine is probably getting a bit tired by now anyway.

Search mate - many people here have upgraded to 420cc's from their 400's. Bigbore kit is usually your old one bored to 94mm and replated, a new piston and rings, and new gaskets that are required. Very cheap.
Now you are talking... What does the big bore kit intail and do i have to set the whole bike up different... Carb, exhaust etc. to handle the upgrade. Thanks again matty
PISTON KIT: Wiseco #4650P8
GASKET KIT: Cometic #C7401
It would be a great time to throw in a new cam chain as well. Easy to put together yourself, just cam timing and valve clearances would be a bit of a bitch but if you take your time and great care...........
You will have to set the carby up different, more fuel required I would say! Exhaust can stay the same.
Bigbore kits there in USA seem to cost around $300 to $400. Full engine service with new valves and stuff from around $1000.
Have you tried to YZ time the cams in your bike? That is a great performance boost, free too.
