So how does the gtyr sound i do like things directly from yamaha so yeah, how much lighter is it than stock, i know hmf is 7 pounds like

 

I dont know exactly because I never weighed them both, but it is a lot lighter than stock. If you want to hear how they sound in comparrison check out youtube.com and search for wolverine 450. You will find a sound byte of both the hmf and GYTR compared to a stock pipe.

 

ok i listened to then and i think that i like they gtyr lol, it does have the spark arrestor correct? don't want to get fined lol also which jet kit allows most power in this?

 

Yhea it does have a spark arrestor in it. The jet kit does not really allow power it just supplies you with the fuel to make the power, Dynojet includes instructions(for what little they actually tell you.) but you could just go buy the jets at your local dealer.
I used the dynojet because I have not ever rejetted a carb and I would rather have some instructions to go with.

 

oh ok dynojet kit...if i get the gtyr exhaust and then a k&n filter, what will i have to buy?

 

That should be enough to get you some more power. If you want to add a EPI clutch kit then you will have a little more low end torque as well.

 

do i just ask for a dynojet kit for 450 wolverine, and where?

 

Well your local dealer can get it for you, ebay, or from www.dynojet.com

 

ok i found the kit, but i was reading and it says i have to drill something....i don't like that....

 

Well I will tell you a secret (I did not drill mine and I have had absolutely no problems)
