Does stock head pipe make as much power?

[OakleyFreak]

Some say that just decatting the stock head pipe is the way to go. Less torque loss  vs True Duals
I opted for Crusher True Duals and the 4 Inch Rineharts.

Not sure how much better it would run with a power pipe or a decatted stock
But Im happy with it, we were in the Ozarks over the weekend
The bike pulled good in the hills with a full load.
So Im not sure how much torque I left on the table with switching to the true duals. I really didnt miss it if I did

A good person to ask would be Steve at Fullsac.  I know I've seen info from him in the past about this same question, and he offers decatted stock pipes as well as his own designs.

Steve puts a X into a stock head pipe so not per say a decatted stock pipe..

I did tune a bike with V&H slip ons with stock head pipe, then de catted then V&H pwr duals. The complete system was right at +10 on both sides. Stock head pipe vs de catted with same mufflers  minor change . +/-1-2 .. on a chassis dyno thats not going to be a bench mark one way or the other.

I have seen a few other sheets showing a bit more but I have no idea if it was a back to back tune. The tune is the big deal .

I have also run the fulsac system vs 100 stock same type of results . I really like The DX + 2.0 cores for builds works very well.

If I can get some time today or this week end I will see if I can find those sheets and over lay all of them on one.
