The HMF utility series with quite core sounds real good IMO. If you take it out, it gets a little loud. I got some good gains with my set-up. You should look at some clutch mods, a jet kit, and an air filter. Just my 2 cents.

So it'll be K&N, Dynojetted, HMF slipon, snorkel kit, and soon a clutch kit when I can get my wife to let loose of a few bills for a set of Mudlite radial XTR's with ITP 14" black wheels hr>
If you get that HMF make sure to get the quite core/ spark arrestor....it reduces the noise level enough that I use it when I go hunting. Just a FYI.

I wanna do some fun little mods on the Grizz and am wondering which slipon to use?
So far I'm thinking FMF Powerline or Supertrapp I.D.S.-X
problem is I don't know which would work better and which would make it LOUD! I don't want a loud bike!
A low snarl like that sexy AC650v2 sound! I know I can't make the sweet sound of a twin but something along those lines BR>
(easy v2rider, don't get all wooded up!)

Well I got a K&N filter and Dynojet kit enroute!
First mods I've ever done to this Grizz BR>
Next in line is gonna be the stock muffler mod (bigger endcap drilled baffles) that way others won't be able to tell that I've done anything to it.
Also in line is a snorkel kit. I like to play in the deep stuff! So this is gonna be a nice thing.

I read it on here but have not done it myself
What I read was you take the end cap out and the tube your talking about then look up in the exhaust and you'll see some baffles...you need a long drill bit (they was using 1/2 inch) then drill it full of holes, one dude did 6 another said 10, so I guess it doesn't much matter just whatever you feel like..
I would think you could also drill larger holes yet, a 3/4 inch hole should move more air than 2 holes 1/2 inch.

how much of the tube did you cut off btw?
All of it? If so then I'd prolly get one of those end caps off Ebay or weld on your own 2" tail pipe

Ok thanks!
That is what I was wanting to know

Hey DD I have done some mods to my exhaust as well. I took a band saw to the four inch piece pipe on the inside of the tail cap, then took a grinder and smoothed over the area where I cut it, rolled it real nice with a air grinder with a small tip, my neighbor has a engine building shop, I have access to all kinds of tools. It definitley helped my low end torque. My question is what did you mean buy drilling the baffles? It maybe something I want to do. Mine is still pretty quiet, so a little more noise would be ok, and anything to help performance wise would be nice, without buying a new pipe.

I cut off the whole thing, I will check the baffle in the front of the pipe. Ihave some long drill bits. Thsnks

DD I drilled out the baffles on my Kodiak last week. I used about a 5/8 drill bit and put about 5 holes in it, and I think it really helped. I haven't really ridden too much the last week or so since I did it, and I need to check my plug to see if I am too lean now. One of the guys at my neighbors shop wants me to pull the head off the Kodiak so he can port and polish a little, he did one on a 400 ex last week and he did a really good job on it. Do you, or anyone, know if they do a big bore kit for the Kodiak? Thats what they were doing last week, bored the cylinder, then heated the jug, froze the new sleeve, then dropped it in. Then honed with a honing machine, really cool stuff, and really improved the hp of the 400ex.

Check out the Big Gun with the quite core I have heard they are great and that you don't have to jet it if you don't want too.
