I currently have stock chatted head pipe with rc componets 4" slipons 2.5 baffle it is to damn quite. Would adding true dual head pipe make it louder and how much. Also thinking of going with V&H big shot duels which would be louder out of the two choices.

 

You know...loud's OK for the first few hundred miles and then the ears start ringing. Not saying you want the bike uber quiet, but semi-loud's best for the long-haul. You can (1) throw a bigger/different baffle in your pipes, (2) get set of TD headers, or (3) complete TD exhaust swap. If you want loud and decent performing TD's, give MGS a call...

 

Yes True duals would diffidently make it louder vs a stock header pipe. Go hang out at bike night or some kind of bike event, look for what you want and take a listen in person.

 

I had the RCX-Haust mufflers with the cat.converter still in head pipe on my '12 Road King. The mufflers are the best sounding that I've heard with the cat. converter still in. But I wanted more performance, so went with a V&H Power Dual pipe along with the RCX mufflers. Sound level and performance increased.

Gut the cat. converter. It acts as a muffler and robs power.

 

Buy some unbaffled slip ons, you will have plenty of sound then!
