Video-Do you have Vance & Hines pipes and/or slip-on mufflers on your Harley Davidson motorcycle? Are you looking for a little more sound out of them? In this video, we show you how to remove the baffles, remove the fiberglass packing from around the baffles, & put the steel baffles back in.
Note: We cannot know the laws for every State and locality & they are ever changing. You are solely responsible for any exhaust changes or modifications. You are responsible for being in compliance with the laws in your area.
This will definitely increase the sound coming out of your Vance & Hines mufflers. We did this project specifically on Lurch's Vance & Hines Titan 450 Oversized Slip-On Mufflers that we installed on his 2015 Harley-Davidson Road Glide Special some time ago. They sounded great, but he wanted a bit more sound and we got it!
At the end of this video we do a full comparison and how the pipes sounded with the fiberglass packing in and with it removed!

Is remapping necessary when switching out exhaust pipes?
We would highly suggest it.
Wondering what map would you run if you pulled packing/baffles ?
Jake,
We ran the map for the mufflers then did an auto tune. The baffles are still in, and only the packing was removed. You can always contact Vance and Hines for a customized map.

If I take my packing out would you recommend a mape from V&H or would you recommend just doing the auto tune?
Thanks,
Jim
Really don’t need to do anything if you don’t want. Removing the packing really doesn’t change the “flow” of the exhaust much, but only sound. I’d just run a quick auto tune. Probably won’t notice a thing Jim.
I removed the packing from a 2015 SGS with Vance and Hines High Out Puts along with Vance and Hines Power Duals. I have the Harley tuner, my question is will it affect anything with the tune or performance? I definitely noticed a change in the tone for the better, and as far as low end/high end power or performance I can’t really tell while riding. Just looking for any info or if Lurch has any update after running this setup over an extended period of time now. Thanks guys.
Randy,
My experience is the same. The only difference is in sound. The OS 450s have a true baffle. My bike is running great and all is well.
~Lurch
How do I remove the packing from my Vance and Hines true duals?
There’s no packing. Just metal baffles.
Can you take padding out of twin slash pipes? Do you have video on that?
Mike,
The twin slash rounds have only a metal perforated baffle, no packing. You could remove the metal baffle, but you wouldn’t have much back pressure.

Can make my vance and hines pipes sound louder
I have a 2013 HD Wide Glide with the Vance Hines Tommy Gun exhaust. I can see the baffles inside but just wonder if anyone knows if it has the packing in it that I could remove to give it more sound? Thanks
I have a 2016 HD Wide Glide with the Tommy Gun exhaust from factory. I would like to have more sound. So I’m planning to remove the packing around the baffles to create a louder sound? However, will it affect the engine torque/power?? Will I have to purchase a fuel pack to tune the bike?
We always recommend tuning your EFI after any exhaust or intake modifications for optimum performance and fuel economy.

Removing the packing affect heat insulation? Will it in time discolor the chrome finish?
No, many mufflers don’t have any packing at all.
Is that video with the stock headers? By making this adjustment to the exhaust won’t the newer bikes computers automatically adjust for this?
Chris,
Yes the headers were stock at the time of the video. We recommend adjusting the map anytime you make a change to the intake or exhaust.

I have a 2019 Road Glide Special, put some Vance and Hines slip on, but they are too quite. I have the screaming eagle tuner and intake on it. Can I take the baffles and insulation out? Is this going to damage my engine?
Removing the insulation (packing) won’t. We don’t recommend removing the baffles entirely. You’ll lose back pressure and definitely performance.
