Hello, and welcome to CVO Harley!! These guys got you covered. My preference on a bike like that: Vance & Hines Big Shots Staggered, Arlen Ness Big Sucker air cleaner, and whatever EFI management system floats your boat. I like the Vance & Hines based on my experience with them on a softail. Very nice sound, but you might want to pull the stock baffles and install V&H Quiet Baffles. They'll knock the sharpness off the sound plus about 3 db and still provide that awesome V&H rumble. The Ness Big Sucker will allow you to flow gobs of air through your engine. Torque and Horsepower centers around how effective and efficient your engine is at moving air. The Big Sucker will do that. Take your pick on the EFI managers. Screamin' Eagle Race Tuner (SERT), Power Commander III USB, or Thunder Max in open loop, or add the Auto tune for closed loop.....and if you go that route, get your pipes with 02 bungs. There's plenty of experience here to guide you. Again, welcome aboard.
