My buddy just got a brand new grizzly 660 and he is wanting to do a few things to wake it up some. I was thinking a pipe, jet kit, and something for the intake side, any recommendations. His brother has a raptor with a DMC alien pipe, and he is worried that the grizzly will be loud like that will it be. He is gettin a lift and 28 inch mudzilla tires and he really wants to be able to spin them without a problem, whats he need.

 

let him know,that the zilla's are about the best tire for the mud,,,,but are pretty much worthless,and down right scary on the pavement,and not very much better on the trails,,,i ended up getting a second wheel kit with the kenda bear claws for a more everyday tire,yet still on the aggressive side,and love them,,,,and if we are going to be mudd'n i can have the zillas on in 15 minutes(kept them on the rims,because they look awsome on them,so i ended up getting a new set of rims for the claws)

with a 28' wheel kit,he's also going to need a clutch kit,and i strongly suggest some 1.5 wheel spacers on all four corners if he is serious about the lift kit (probably a good idea with just the 28" wheel kit),and with the spacers,he's definatly going to want an over fender kit

as far as the intake,,,,,get the pro flow K&N kit with the flange,clamp on filter,and outerwears

and the pipe,,,,i chose the Dubach (Dr. D),and it has a great sound,deep throaty,but not irritating,however it is a good bit louder than the stock one
