Not baffling... Really
Got curious today and took the baffles outta my V&H BSS on my street bob. Took a little test ride the bike lost a good 30% of low end torque. Now I've been riding enough years and tinkered with enough bikes that I knew it would. Mostly just wanted to hear the pipes unbaffled really (didn't sound as good honestly, just a little louder) Picked up a little on the top end but not much. so let that be a lesson to the new riders, if your pipes have baffles leave them in, you will lose power. I ride more aggressive then 99% of the riders I know and still don't find the tiny pick up in the top end worth the loss of a good chunk of low end torque. Not really worthy of a new thread but I had to tell someone

See I thought about that... I mean a different baffle. But I never keep an exhuats for no longer than 1 riding season anyhow, so didn't figure they're was any need. She runs good the way it is and it'll be a different exhuast next year any how. Glad that the DK Thunder torques worked for you though. That gives me another option in case I decide to keep them a while

I've found the same, DK Custom W158 TTI's in V&H Big Shots Staggered with baffles removed, the sound is much deeper than stock, that bright rasp is gone and the low end and mid range is back; if you want to remove the stock baffles this is the only way to go!

Thunder Torques are an inexpensive solution to getting your low and mid range torque back but, i do understand if you change exhaust frequently. It is always good to know you have other options

The TTI's are not like stock baffles. They are installed similarly, but the outcome is a huge difference. The type of material, shape, size, thickness, & surface coatings all make a difference in how well the Thunder Torque works at increasing exhaust gas velocity.
The TTI's obviously have their genesis in the simple lollipop concept. But they are quite a bit more, especially the W series.
Technically exhaust systems cannot increase or decrease an engines power. However, and this is a BIG however, exhausts systems can have a profound effect on increasing or decreasing engine pumping loss.
The Thunder Torque Inserts have a proprietary shape that is much better at increasing exhaust gas velocity, thereby reducing reversion, which reduces engine pumping losses, and increasing inertial scavenging. Net result is a significant increase in power & torque in the low and mid range Without sacrificing any top end.

I swap out my pipes after every ride over 20 miles.
