I bought a new RKS yesterday (my 8th and probably last Harley). I discussed getting a full stage 2 with the dealer when I picked it up. I have always done that. I know this may seem crazy, but Im wondering if its possible (meaning it doesnt screw anything up) if I get just the torque cam, and maybe a tune, but no new exhaust. I kinda like the stock sound. Not popping and roaring, just a nice smooth sound. Has anyone done that before?
If you keep the stock exhaust you will limit the power you get. However, you will need a tune to get the bike to run safely and without problems.
Thanks. What Im looking for with the torque cam is like switching to the sport mode in bikes that have multiple modes. Im not looking to max the bike out, just get that extra boost at low RPMs. I definitely want the bike to run safely so this may be a bad idea.
Back when I bought my first Bagger, as a new vehicle, back in 2012... I had a Stage II and some other mods added by the dealer within 30 days of delivery (long story, as I usually do them myself). The accessories then became covered under the bike's factory warranty.
If you're gonna do it, use all HD parts, and have the dealer install them... might as well get them covered under the factory warranty...
I just checked, and per the internet, the program is still active;
"Harley-Davidson has a program called Custom CoverageŽ which allows eligible street legal Genuine Motor Parts and Accessories to be covered under the remainder of your motorcycle's 24-month factory warranty if purchased and installed at an authorized dealership within 60 days of the new vehicle purchase."

I fully appreciate the additional kick in the pants from a "torque cam." Can make a bike a LOT of fun in the riding zone where you spend the most time. If you're not going for high-rpm, max-effort output and you're happy with the way the bike sounds now, I'd say the exhaust should be fine. A little more air with a filter/intake can't hurt either, as mentioned.
But, be careful. That additional kick-in-the-rear can get addictive and it's a slippery slope!
Or you can lower your gearing with a 31 tooth Andrew’s pulley for a 3% reduction. An evolution industries 46 tooth ring gear and shorter primary chain kit for a 6% reduction.
I explained things to the dealer and he recommended a full stage 2 with basani headers and screaming eagle slipons. That way I get the performance with basically the same sound as stock. Perfect option for me.
OP I like the torque cam in my 2023 Ultra. I used the Screamin Eagle 447 cam to retain my warranty. That being said since you have a second gen 117 look at the dyno charts. The second gen M8s seem to have a hotter cam from the factory and don't benefit quite as much from the torque cam as the first gen motors like mine do.
If you want it I'd still do it, but I was surprised at how much more power the second gen M8s get from just a stage one.;
