What I haven't been doing and will now practice is getting my RPMs up, clutch to the friction zone and synchronize the two as I power out of a stop. I've just been letting my clutch out, rolling on the throttle without loading up first as I'm waiting on a green light. Now I've got something new to work on. Happy riding, y'all!

The fatcat is a hp pipe. Not a torque pipe. Gotta use the right exhaust for the results you're after. The fatcat isn't the best pipe on both ends. It can't be. No exhaust can be. It wouldn't be any better than his V&H slip ons. Probably worse. In fact, a good set of slip ons will usually do better for low end torque than just about any 2in1. The Khromewerks HP Plus slip ons do very well low end and midrange. So would Rush with the 2" baffle. I've got the 2 1/4" baffles and I have more torque off the line than a similar setup with the fatcat. Like 15ft.lbs. more. But the fat cat does way better hp in the upper rpms. Can't be hp king and torque king. It's just not possible. And the fatcat is thee hp king. Can't for the life of me figure out why people wanting low end torque go with that pipe.
Even the Pro Pipe will do way better low end torque than the fatcat.
That said, I'm not sure you'll get enough of what you're after with just an exhaust change but you sure don't want to go backwards either.
Fatcat vs. Pro Pipe
^This would be a good idea^
30 tooth compensator eliminator from Evolution Industries .
^Even better^ Gotta get up mighty early to take me off the line.

Howdy,
Does anyone have a recommendation on pipes that will increase my torque and HP especially from full stop? I currently have D&D headers and V&H oval mufflers and a 110 Screaming Eagle motor and a Baker DD7-seven speed transmission on my 2012 FLHTK Ultra Limited.
I'm dyna-tuned with a TTS Tuner. It just seems that others are off the line from a stop and it takes me full throttle to catch up.
Any one have experience with Fullsac headers?
Thanks

Appreciate the suggestion 60Gunner. As I understand their website, all that is necessary is to change out the stock sprocket and replace with the 30T and longer supplied chain and no other mods needed; put back together and done?

Yep. That's it. Took me about an hour and a half start to finish and I ran it without the primary cover a minute or so to see how it tracked.

In post #10 you seem to of sorted it out. I was going to add do you know at what rev range your engine produces its max torque?
Many people seem to fit pipes that just make a noise and find they lost bottom end. In that case you would need high rpm to find torque for a quick get away.
