looking into getting an aftermarket header to finish up some mods over this spring....

the two maybe three things i want to get to go along with the rest ive done so far is an aftermarket header + can, a set of cams, and possibly an aftermarket ignition setup.

so far ive done the xb 12 pistons/jugs/heads in stage3 with the billet mount.

so far the top end has made the engine feel smoother, but i feel as if ive lost some torque down low but maybe picked up a few hp up top. not even close to the gains i was hoping for.

i know the cams will bring this motor alive, but i feel i should do the header/can as well, since my header is the stock 96 s1 header with a few dings in it from being laid over by the PO. and the can (V&H) is in sad shape.

so any reccomendations of a set of cams/header/can?

ive been thinking about just taking the bike to a fabricator (have one in mind) and having him make a set of custom pipes for it, but i would like to at least have some kind of specs to build off of.

Ricky, I've thought of the custom header idea a few times. I don't have anyone local in mind though. You could use the stock header as a template/base, and have the primary tubes extended around the front of the motor, and put a collector and reverse cone megaphone at the end, so it would be similar to a Force exhaust, but in stainless. Longer primaries will take the dip out of the lower end, while the megaphone will be sickly loud and make plenty of top end : D. BTW, I would get cams first probably though.

Before you invest too much here I would recommend that you have your bike dyno'd. It's a very small investment and it gives you an idea as to where you want to improve your bike.

If you have hole in the low / mid range, then "hot" cams will make the problem worse. Also a typical "stage 3" involves larger ports which "typically" reduces low to mid range power.

So spend a little money to see what you have so you know where to put the rest of your cash.

As for aftermarket heads, I think D&D or Buell Race Header is the way to go.
