Looking for a "STOCK" YZ400 exhaust system.

5 posts in this topic

I am looking for a "STOCK" YZ400 exhaust system. Does anyone have one they want to sell or trade straight-up for my FMF Powercore IV S/A and the FMF oversized headpipe?

The FMF combo makes tons of power, but I simply can't use all the extra "beans" as I'm strictly an Arizona trail rider. Our trails are typically very narrow with a lot of tight switchbacks.

Thanks,

Jeff

How about a stock WR system. It's got about 10 hours on it..super clean and unaltered!

Bill.

I need more info than what you provided.

What year is your stock WR system? I have my original 1999WR one, and it is a really nice boat anchor.

Also, I have never heard a 2000 or 2001 stock WR exhaust , so I don't know what the noise level would be. The noise factor is one of the elements I am trying to improve.

Ideally, I want a YZ system, because there's a company that makes a bolt-in insert that allows the pipe to use FMF 's Megamax discs and endcap.

This way, the pipe would be tuneable, AND have a legal spark arrestor - the best of both worlds.

Jeff,

I have a stock head and muffler section from a 98 YZ400. $100.00 if your interested. My e-mail is ccrowell7587@uswest.net. Let me know if you'd like to come by and see it. I live at 51st ave and Greenway.

Pretend it's flat and give it the gas.

Jeff,

I think the guy I bought my 98 YZ400 from still has the stock exhaust. He'll be back Sunday evening. I'll check with him and reply again tomorrow.
