seeing as though the 2007 race season is getting closer and closer, i've decided to finally swap my pipe out for a new one. i currently have a tc short pipe on my hybrid, and seeing as though the shorty pipes no longer meet the db rating at the races, i was wondering what other pipes work on these hybrid? i am all set header wise b/c i can just use the one that i have, but i am wondering what silencers off of which quads would fit a 400ex framed yz426?


thanks,

I have a white brothers R4 muffler i will trade you. Its on my yz426 hybrid. The r4 is said to be the best pipe you can get for it over on thumper talk.

If you have a welder and know how to use it, anything will fit. ;)

I had an HMF on mine..I had stock YZ headpipe, custom mid-pipe and 400ex HMF rear section.. not a slip on though.. it was from the full exhaust.
