I know HMF makes a pipe for the grizz. Does anyone else? Please let me know if you have installed one as well and what your butt dyno tells you.

 

hello

 

i have only heard of people getting hte hmf exhaust for there new grizz's. i have not heard of anyone getting anything else.

I've piped my Grizzly with the HMF, put a dynojet kit in, and K&N airfilter with a modified airbox. The difference is night and day. With my 27" Bi/Tri Claws, it will stand the grizzly up on the rear tires when you stab the throttle. The power difference is impossible to describe. I went this route to gain back what little snappiness I lost with the 27" Claws, let me tell you, I got more back then I ever lost. Simply amazing.

My dealer says they don't list a K&N Filter for the grizz. They do however list a jet kit which I ordered. What filter did you use?

 

thanks Silverbear. Your rig sounds awesome. Where did you pick up your HMF stuff and all?

Your dealer is correct. The clowns at K&N still haven't got the right filter out for the 660, and last I heard it could be a couple more months.

I was holding off on all these mods until the K&N filter was correct...well they lied to a dealer, dealer passed it onto me, I ordered everything which all came except the K&N. The dealer called me and told me K&N really didn't have the correct filter for the 660. what did I want to do. I knew others were usuing the grizzly 600's filter, just trimming the plastic a little to make it fit tight, so that's what I did.

Not a problem. I got everything from East Kentucky Motorsports , they don't list the HMF on the web, but just telephone them on their toll free line, and ask for John.

silveebear-
How much did that whole order cost you. with the hmf pipe, dyno jet kit, and the K&N?

 

Silverbear

How much trimming did you actually do? Did you have to modify the stock airbox or did it fit ok. I really want to add the K&N when I do the jets. Would you possibly have the part number? I always worry that a bad seal will let dirt be sucked in. $$$$$$$$$$$ You get my drift.
