I would like to add a Sno-Stuff Rubble Pack to my F7. Is this something I can just add on, or do I need to make modifications to the clutch and add an EFI controller? Any insight you can provide is appeciated. Thanks!

Leave it stock.. Depending where you ride it will save you money and keep trails open......but that's just my 2 cent.
I have a D&D Y and Black magic pipe and stock can and it has a more throaty sound, but not as much as a rumble pack and at times its to loud.

i'd say GO FOR IT but thats me... to me the sound is half the experience

mine

go with MBRP it imo has the best sound by far

i wouldent recomend a can on any firecat , just my opinon they dont gain hp even though they say something stupid like 2-4 hp gain , on firecats you actually lose 1-2 hp it was even dyno proven so do you really want performance or do you want to be anoying loud, take the money for the can and buy a clutch kit , a clutch kit is actually worth the money and could be one of the best things you ever did to your sled

for what it is i have a brand new sno stuff can 4 sale.

I you ride trails don't do tha can and get either a pipe or a clutch kit. If you don't ride trails and you do add a rumble pack it doesn't require any further modifications.

you will lose HP with a can on f7 spend the cash on clutching!then have your head cut and then thay wont hear you coming as you pass them by

D&D can or speedwerx, both are fairly quiet and will keep you in good graces with the neighbors, had the mbrp on my F6 and after i sold it to my friend i got to hear it like when someone else rides it, it's the most annoying thing ever

i hear that the Jaws Can doesnt lose power. but i dont know for sure

I have a sno stuff can on my F7, and I am getting rid of it cause I think its too noisy. Not worth the noise to loose a few horsepower.

i have a D&D can for sale. I had both D&D and MBRP and MBRP was pretty obnoxious. D&D doesn't lose any power and has a descent sound.
