hello ppl, i just bought a 2006 grizzly 660, and i have some plans for more power upgrades, now im not trying to make this quad into a:Brute Force, Polaris 800, or outlander 800, if i wanted that i would of bought one of them....the griz is just my personal preference, i wish it had efi though...beside that i have done some research on some upgrades that are in the budget: K&n power kit thats with jetting, procom cdi box/ rev kit,outlaw sd clutch kit, NGK performance spark plugs, and "power now".... for exhaust i contemplating between the: pro cicuit t-4, HMF utility, and IDS supertrapp, i also heard some great reviews on muzzy's exhaust but not sure if its for utility, anyways if anybody can tell me whats a waste and what not, and if all these products can work coenside with one another it would be greatly appreciated. and also if anybody out there knows of the gains i will recieve can u post them.

 

There is another Forum called ATV Owners.com that has a section just for Grizzly owners. Those guys will be able to tell you how much of that stuff is a waste of money on the Grizzly. If you go to that site, tell them Starky says hey and my server is still blocking me from using that site.

 

Starky I'll tell everyone you said hello. I was wondering where you've been.

 

Talk about a pisser. I can go into ATV Owners and get on all the forums except the Grizzly Forum. I'm waiting for the server to crash so that block will go away. One day I was able to get on it and post a few pictures of the Griz with the tracks but then the server wouldn't let me back in.

 

I have an white bros. E-series pipe for the Grizz along with extra discs and a quiet core insert. I tried the pipe on my Grizz......make a big difference but man the noise was to much and thats why I am selling it. I do to much hunting for that!

 

I have a k&N power kit it helps a bit.

My question is on the CDI boxes do does anybody know how they work?

 

if your going to buy a pipe for a grizzly get a white brothers e series, ive had one on my grizzly for a year and it givs much more hp/torque, plus its alluminum so it will never rust, and its legal but still has a nasty bark

 

i also have a 155 main jet, and a white brothers power filter.......my stock grizz did 65 with the pipe,jets,and airfilter i can get to 68 pretty quick

 

How much do those white brothers e series exhausts run? Do you have the entire exaust or just the
slip-on?

 

I have just the slip on and they sell for around 300 bucks new, I will sell mine for 150$ plus the shipping and thats with 60$ worth of extras as well.
