01 wr exhaust packing

11 posts in this topic

I believe this is true, the WR does not have any packing because it is a baffle type exhaust. I have never actually taken one a part to see, but I am almost positive that I have read it somewhere. Hope this helps.

How did you get it apart? I have a wr exhaust that I cut open, but not sure of the year, I think 02. It is a sealed unit with no packing, just chambers.

This is true. If you take the end cap off, you'll see a screen welded to the inside of the canister. There is (theoretically) some permanent packing under the screen, which is not removable. I have an 02 WR426 and wanted to quiet the thing down a little with repacking, since that is not an option, I ended up getting the GYT-R quiet insert.

Yep, an uncorked WR426 with a stock exhaust comes in over 100 dBA using the AMA sound test guidelines (3400 rpm, 20" away). With a GYT-R quiet insert it's 90-92 dBA using the same test procedures.
