Default stage 2 upgrade

Recently I did a stage 2 on my 2017 Road Glide Ultra. The rs 468 with adjustable push rods, lifters, cam bearing and new oil pump with backing plate. I had street cannons that I didn't replace and stock head pipes, k&n high flow ac, TTS tuner. The results were not what I hoped for but the sound was awesome. I believe the rs 468 cam is what I want in my bike, therefore, I ordered S&S mk 45 slip on mufflers, and jackpot 2-1-2 head pipes no cat. I saw the fuel moto cam shootout and they used exactly the setup I am finally doing and I'm optimistic that I'll be happy with the result. I'm waiting for the head pipe and then my bike goes back again. I'll be selling the street cannons and I'll have my stock head pipe de-cated to sell with the street cannons. I'll keep you posted on the final results.

Yes those catted headers will shut down a bit of the power the cam and tune would give you. Once you get those headers on, it'll be like a different bike.

If it were me, I would leave the cats intact when you sell them. Some ppl may be looking for stock head pipes with the cats. Others might want stock headers so they can decat themselves.

Do you have a dyno run you can post now? You say the results were not what you hoped for, how so? The mufflers and Jackpot 2-1-2 will make a difference, but I would have just decatted the stock head pipe first. It might have got you where you were looking to go. Here's mine with the stock head pipe decatted and the RS468. I was running the stock muffler cans with Fullsac 2" cores and an Arlen Ness Big Sucker.
