I love the sound of drags on Shovels! You can put a 1/4" bolt through them to break up reversion and help a little with performance.

You make lollipops and put them near the end of the pipes.

They keep down the reversion in the exhaust, this keeps from fouling the intake charge with some cams, and also gives a little back pressure to aid in low end torque. I use Eyebolts and weld a fender washer to them.

I hate to tell you, but those are technically not drag pipes. Drag pipes have no muffler body.
Easy enough to tell if yours have baffles, just look inside them.

For reference, these are drag pipes:

I think they are Cycle Shack and they call them a Slash Cut Muffler Pipe Set

Weren't Cycle Shacks slip on mufflers?

Pythons or Paughco were one piece like those?

I don't see any shovelhead pipes listed on their site anymore but these Softail slash cut are not slip-ons.  I don't doubt there are others making similar exhaust systems though.

If from the dealer than they are probably HD "performance" exhaust, before they started calling that stuff Screamin' Eagle. Which, by the way, were made by Cycle Shack...

And yes, Cycle Shack made one piece pipe/mufflers, used them for long time. In fact have a set on my '77 FLH. Bummer about Cycle Shack. What a loss.
