Nah. I have a delkevic short without the db killer, I find it sounds cool and I can hear it with earplugs, but its gets a bit quiet in heavy traffic once the bike is hot
I tried just the midpipe both to see if it would be much louder but also to show off the rear wheel better, and if I liked it I was planning on getting a pipe made with a better angle. It sounded a bit tractorish so I didn’t bother. Coffman might be the answer but its overpriced
