I have a Supertrapp Supermeg 2 into 1 on my bike. It is a 95" with S&S570 cams and head work. Makes over 100 hp and tq. 1999 Eglide classic

 

V/H Big shot slip on's with stock header pipes...stage 1 air cleaner with race tuner..
nice sound, not to loud and not to quiet...

 

Ever heard of White Bros. e-series 2-1? The white unicorn of performance pipes.

 

Vance and Hines Dresser Duals with Rush 2.5 mufflers. It goes from pretty tame at idle to pretty radical. Here's a sound clip.

Fat 3" True Duals...with no clamps!

 

In my Sig.

 

Here's another vote for the Rinehart True Duals. Loud if you want them to be, quiet when you need them to be.

I had SE touring performance slip on's with AC/stage 1 and switched to Vance & Hines 2 into 1 pro pipe. I could notbelieve how much more lowend torque the bike made just from that change alone. To make sure it wasn't just me my brother rode it before and after also with same comment. This is on a 05 Road King Custom.
