I dropped coin on the V&H Torquer 450's. This off of DK's site. Haven't put the TTI's in yet... but I do love the sound of the V&H's right now. :D

The all new game changing Torquer 450 produces the Best Sound, Best Performance and Best Style for your Milwaukee-Eight Bagger. Don't Just be seen, Be Heard! Perfect for ramping up that sound. features blue proof technology and a CNC machined billet end-cap for an impeccable appearance.

It’s also just the right fit for CVO models with extended saddlebag skirts.

Vance & Hines’ race inspired performance and traditional hot rod sound set this system apart. Baffles, mounting hardware and easy-to-understand instructions are included for a hassle-free, perfect fit every time.

I did the same, and I also was disappointed with the sound at first. The sound seems to have improved, however, and my neighbors hate me as much as they ever did.

If you have a great aftermarket cam, the sound is very satisfying.

I have the 4" Touring mufflers, which IMO are the best sound cans they have.

I decided to pack my Rineharts with SS mesh wrapped around the baffle, followed by fiberglass baffle packing material. This restored my low end torque and added a nice low toned rumble. Nice on the ol' ear holes on longer rides for sure!

Rinehart with TTIs fan here...

I started with a set of V&H Power Duals and Torquer 450s... Super loud and lost my low-end.

Installed TTI-258s... Quieted things down a bit, got all my low-end back and then some. Didn’t much care for the new tone...

Swapped-out the Torquer 450s for Rinehart MotoPro 450s. Loved the tone, low-end needed more...

Installed TTI-158s... Golden! Got the low-end where I want it and quieted them down just a bit without significantly impacting overall tone.

I didn't do any testing before and after but I do know those open slip on's will take away some torque. Seat of the pants is that I picked up a little power in the 1800 to 4200 RPMs and they sound great! Here are some pictures for reference. They are approximately 1.75" from the end of the baffle inward. I dont think they are too noticeable visually because nobody likes looking up the exhaust pipe and seeing those lollipop's. But they function well, plus I've heard M8's are finicky with exhaust configurations and reversion/ back pressure.

Just curious what size drill bit you used and what diameter the bolt was? Thanks

Pretty sure it was a 5/16" bolt so clearance would be .323.
Real Simple as you just drill thru bottom of muffler and on thru baffle all together and drop in from inside.
The deeper you go the trickier it may be to drop it in the hole.
They are very good quality and do as advertised.

awesome thanks man. So I’m assuming you did not need the longer thread option?

Have installed them in Rinehart and V&H and no, did not need longer stud.
A longer stud would only be needed if the distance from outer pipe to inside baffle where insert mounts was huge. Like a huge muffler and small baffle.
If you tell DK what you have they will get you what you need.

I'm running the Rinehart DBX 4.5 and was not super happy with the sound and loss of torque. After adding an S&S 475 cam and the Fuelmoto tuning inserts, all is right with the world... Beautiful, classic, V-Twin sound and most of my low-end torque restored.. interestingly, Fuelmoto's inserts are rectangular rather than round, like the OP's.

Thought I'd include the FM link. I'm running the universal fit.
