Swan (Michigan) | May 6th, 2021
I went from 3.5 in straight exhaust to 4 in Turbo back with MBRP performance muffler to now using the Quiet Tone. The MBRP performance muffler was just too loud while pulling my 35 ft travel trailer. I am very satisfied with the Quiet Tone as I can still enjoy the turbo whistle and not worry about making too much noise when needing to punch it. Great sound reducing muffler.

Put it on a 15 Duramax and she purrs nicely and has zero cruising drone but nice sound when you get on it. Quiet and almost sleeper when cruising. Exactly what my middle aged father was looking for. Two thumbs up!

I have a 6.7 Powerstroke with the BD power scorpion kit. The 4” straight pipe too loud, this muffler knocked it down to the perfect tone. Love it.

Questions and Answers
Drone level Hi, I just installed a MBRP 4'' S5259AL, and the drone level on highway is unbearable. Will this muffler reduce drone level? Or should I get a resonator instead?

Answer
The MBRP UNIVERSAL 4" QUIET TONE MUFFLER/RESONATOR will be one of the best options currently available to cut drone/exhaust noise without reducing horsepower or increasing the exhaust gas temperature.
I see overall length is 30", is that tip to tip?
