Title: How to quiet down HD Street Cannons
Post by: Lane on May 13, 2022, 01:27:30 PM: I recently had the Screamin Eagle Stage IV 131 engine modifications done to my 2020 CVO Limited. I love the boost in power, the thing goes like a banshee now. However I don't like the loud exhaust with the HD Street Cannons on it. I'd like to find a way to quiet it down a bit. The mufflers are a straight through design, so there is room to add baffles of some kind. Anyone have experience with this and can recommend some ideas?

BTW, I would spray them w/ high heat paint before installing them. :2vrolijk_21:

How loud is it with the mufflers. Reason is I’m thinking of doing the 131” in my 22 CVO RG and I have the same mufflers.

Post by: rayson56 on May 18, 2022, 01:02:23 PM: I recommend going back to your original mufflers and adding Fullsac 2" or 2.25" cores and their Tech Mat to quiet it down. It's a cheap and easy fix and you'll love the results. I have Fuel Moto's 128" kit along with some other upgrade and utilize the 2" cores. Tons of low end torque and a really nice tone.
