WR400/426 - YZ400 silencer interchangability?
Posted June 09, 2009 - 07:01 AM
But then I got to thinking will a WR400/426 stock silencer work on his bike? There has got to be a few of those big black ugly oil cans out there cheep as they were pretty horible stock. But with the insert PMB sells for the stock WR can for $40 its gotta work better. That has got to be a cheeper solution for him.
I know when the YZ/WR's 1st came out a lot of the parts were inerchangable. Would the WR silencer work on his bike?

it will work but the mount at the mid pipe will need alittle mod to bolt up , why doesnt he moddify the stock yz endcap and reduce the diameter of the tip that will reduce the DBs tremendesly and wont cost much money
No modifications are required. The OEM exhaust systems between the 98-02 400/426 YZs and WRs will freely interchage between bikes.
If you found you had to modify the mid-pipe bracket, then either the subframe was bent or the pipe was bent.
