Default Modified Street cannons? M8 Softail

Anyone dismantled the street cannons and done a bafflectomy? They clearly can be dismantled, just curious if its worth it. My bike runs so much better with them compared to previous exhausts... jut a touch quiet!

The bike has SE/K&N ventilator replacement filter and a standard load stage 1 tune.

OR

Has anyone made replacement inserts for them?

Cheers!

I did a bafflectemy to the stock mufflers on my 2018 Low Rider. I did it because I wanted to keep the cats while getting better sound. I thought the street cannons were too close to stock sound because although they have a straight through baffle it has a small dia. I put a 1-7/8" louvered baffle in and wrapped it in order to get the low deep tone without the harsh crack.
I sawed the rear ends off and pulled the old baffles out the rear. The cats are separate and stayed in. I had to do a little fabrication to fit the new baffles.
I machined some new aluminum rear caps, nothing fancy. They sound great, not too loud at all. I've been running them for a couple years now and over 20,000 miles.

Be careful that by opening them up more you don’t negatively impact low end torque.

That's what happens when you remove the cat and put 2-1/4" or larger baffles. I didn't do that.
