I have done just about all you can do to n M7.
remember it's just opinions.
Do not do the intake you actually loose perf.
Buy the Skid. It works and weight loss is about 10#
Stay away from cans they don't work. Unless you buy a pipe combo. I have bought 4 up in til I bought a pipe and can from NPP. None of them worked.
RKT secondary is a must have. don't fool yourself with the shift assist.
I have only used simmons ski's but aftermarkets are a good purchase.
Get the fuel psi dialed as well as the oil. I have a Boss fuel controller I will sell brand new for 175.00 I switched to an Attitude for a turbo in the future
vent the clutch to include shock towers.
get the new track [powder claw] it's lighter and works just as good if not better than a A-20 flipped. without crapping yourself going back down.
I have a ton more mods but those are the ones that are cheap and easy. Again just my 2 cents. there are more guys that have other options I am positive of that.
I put the cat race 150 rails under mine with the 09 float set-up. It would be a good idea to trade out your rails and start from scratch.
Remember this thing will eat an m8's lunch prior to 09 and it will be very competitive to the new ones if done right.
