+1 on V&H Short Shots!!!!!

 

The Python staggered duals are basically V&H big shots staggered, which are a pretty friggin loud pipe with the right baffles. I'm surprised no one has suggested the Big City Thunder Monsters yet. I had some big shots on my superglide with those baffles and it was LOUD. It's not an annoying loud, though. You already have a nice set of pipes. Now it's just time to start experimenting with different baffles until you find the sound you're after.

 

I've got Vance & Hines Big Radius 2 into 1 with no baffles and they sound badass. Best way I can describe the sound is a throaty V8. Very nice.

 

I have the V&H BSS with no baffles and they sound nice. Not the loudest I've heard though.

 

get BCT monster baffles for your pipes. Or you can go with short shots, samson street sweepers, bassani pro streets. Those seem pretty loud to me. You can also gear down. lot of guys new to harley tend to ride low in the rpms(in 5th when should be in 4th type of thing).

 

Thunderheader without a doubt. I don't like how they look on a dyna....but they are certianly the loudest unless you have drag pipes.

 

Bassani Firesweep

 

I hate my thunderheader on my '10 fxd... Scraps in corners and can't get the lean in the curves that I want... Guess I need 13" shocks for clearance.

Have them and they are loud Not the loudest though.

The loudest I have heard are probably freedom performance without baffles.

 

I love loud pipes but I'm fifty six years old and my ears ring constantly.
