There is a guy named Derrick at Bikeman in your neck of the woods that can help you with the baffling on that pipe but the cold hard facts are that all the baffling, torque cones, etc in the world wont change the primary pipe length which is where the problem really lies.

Thanks,

Thats what I figured, I will most likely just leave it alone as I probably wont notice the dip anyway. In the future I am thinking the d&d stubby cat would be the way to performance wise while still retaining the side dump.

Low end torque that is MIA is more likely the result of that cam bleeding off ccp, ie over-camed.
With the intake closing number of that cam, 10.3-10.4, would/should be a game changer.
Reason I inquired in regards to the ccp.

Thanks Scott maybe in the near future I will look into increasing the compression!

That cam does work.
We have those as stocking items here and pick/choose their use.

I have a buyer for my current exhaust, thinking of going to the d and a stubby cat. I'm thinking that's my best bet for now and for future performance. Thoughts?

Well I did it, being I had a local buyer for the akrapovic and I know it will help with future engine upgrades I ordered the d and d stubby cat.

The Fatcat may help, but that intake closing number wants more squeeze, for starters, to show it's effect.

That's my next plan of attack to get some more power up the compression and port and polish. I think this pipe should really help smooth out the curve and eliminate that dip. More compression would bring up everything correct?

So we ride enginecycles? Rename the MOCO to Harley Davidson Enginecycles, tell all the MC's they are now EC's HAMC now HAEC. Sure thing.I'm heading out to my motorcycle to do some motor work.
