I can answer the exhaust question. On a std bore no need in changing to pro pipe.
Which cam to go with?
I plan on rebuilding my brute 750 with a std bore kit , i have a pair of new amr XX cams and HC pistions im just waiting to put but im wondering if these cams are the aveune i wanna take, i do mostly woods riding and i am looking for that bottom/mid punch , so before i install these im just wondering is this what i wanna go with, also i have a muzzy std right now, should i upgrade to the pro for this build.. is it worth it basically all input is appreciated
thanks jason

You will be happy with those cams.
They are great all around cams.
I drag race with mine even though they are more suited toward trail riding.

Like asnow said, you'll be happy with that setup. that is 58-60 rwhp bolt in kit.
On a standard bore with XX cams. Hell yes, the muzzy pro will make 3-4 hp over the standard, I've dyno'd it probably 30 times on different machines. It does that on a stock machine.
ask anyone who has run a standard and a pro.
That's why Muzzy's is going to discontinue the standard pipe. As even on a stock machine you get more HP with the pro. 44-46 rwhp vs 48-50 rwhp There's dynochart comparisons in my forum somewhere.
the XX cams are a high rpm cam so you need to have that motor breathe for max performance.
If you don't have a programmable dyna, run a 6 key and the Dyna together. the XX cams love 39 degrees timing. and you can still run 93 pump gas this will help the low end.

alright, thanks looks like im gonna stick with the XX cams and go with the muzzy pro, also i was on diamond g's website and there 2 degree keys one for 25 and one for 30, does anyone know which one is the 6 degree?
Just remember dyno numbers don't mean jack. A pro pipe might yield you higher HP numbers in the higher rpm but your 0-25 mph times will suffer.
John, what did you set the timing advance on Skip's AMR 800, ON THE INGITION MODLE? I am trying to figure out what would equal the 39 degrees of timing for running xx cams. Mine is set at +5 advance "at the highest value" right now but the motor is stock for now. I should be doing a AMR standard bore in about a month.
