Advice on cam upgrade tc 103?

You don't need a 2in1. A good 212 that uses a crossover or X pipe of some sort will do a good job. And yes longer. Especially low end and midrange. A good 2in1 will likely do more hp up top but not always and many of them suck at low end. There's just as many **** poor 2in1s as any other exhaust.

You could try the TTIs from DK Customs. Not out much if they don't.
Just not sure how they'd work in pipes that short.
Both Rush and Khromewerks make slip ons and full systems that perform really well and have a nice deep sound to them.
They both do extremely well with cams that have a lot of overlap. Cams with a lot of overlap can be a big plus when it comes to cylinder fill providing the exhaust plays well with it. Otherwise it'll kill it.

I ran the Khromewerks HP Plus baffles(dogballs)in a set of drag pipes on my sporty when I first bought it and had great low end but those drag pipes were longer and they actually used the stock hidden crossover pipe so not a good comparison really.
I'll leave you with this. I'm running the S&S 570s in my 2013 Heritage with the 103 and it's because of the 40° overlap the cams have and the Rush slip ons I'm also running that I have really good low end torque with cams that have a later intake open/close (20°/40°. Even before I did the .030 head gasket I was doing 93ft.lbs torque at 2200rpm. More like 100ft.lbs now. Yet I still make power to 5800rpm.
Your low end would be hurting running these cams with those pipes.
My point is choose your cams and exhaust wisely so they work well together and it'll pay off.
