Hello and welcome, you will need more than a cam.

Look up tw-777 woods
That stock pipe has a cat in it just after it goes into 1

decat? But 2 into 1 more for tq which pinches hp a bit

tuner 

air cleaner

His cams are not cheap.......

Check warranty issues !!

pipes, A/C and a good tune are only going to get you about 85hp.
as said above cams, compression and heads will help
may need throttle body and injectors

then you'll need to think about a clutch and oil cooler
have a look at the stage 4 thread

Cheers for reply guys, well was looking at screaming eagle intake Vance and Hines long shots or short.thoughts? Then was going to start with cam heads??

SE211's, 30thou head gaskets, decent 2:1 pipe, A/C, and a very good tune you'll be over 100hp/100tq.

What is that clased as what stage mate ??

Cams for most people would be stage 2.

Heads / Head work for most would be stage 3.

I will let you know next week after i have mine dynoed. i have the 2013 switchback with SE204 cams, full D&D Fatcat 2-1 exhaust, SE air cleaner and power vision tuner. No other engine mods. I'm expecting around 100 hp. The dyno tuner did a street glide 2 weeks ago with same sort of setup and it cracked 100 hp.

 Mates 2012 fat bob has s&s 583 cams, se air filter, v&h long shots , se tuner, 104 up + 113 torque, so it is possible with not much work.
