    M4 Street Slayer

    I put the stock exhaust and servo motor back on. Way too loud (with the supplied baffle installed) plus it drones at highway rpms on a 2019 ZX-6R. That’s wearing earplugs, and a Shoei X14. With no baffle it’s ridiculous. Also, without the servo connected the bike definitely had a tendency to fall on its face off idle and would easily stall if you weren’t aware of it. Exhaust looked great, and it was easy to install and is much lighter than the OEM setup. I’ve been happy in the past with the sound level out of Akrapovic, and Yoshimura but this was next level loud and obnoxious. If you’re a fan of two brothers or brock’s then this exhaust is for you. If you actually want to enjoy the ride, and not have the police waiting for you up the road because they can hear you miles away then maybe consider another exhaust.
