Not “Quiet” tone muffler
2
Installed on my Duramax with 4” exhaust that was straight pipe prior. After installing “muffler” truck has a terrible in-cab drone at 1900RPM. Noise levels outside the truck are quieter but it’s miserable inside the cab. Prior to installation, there was no droning. Quiet tone muffler is a terribly misleading name for this product. The muffler is well made, looks good, and seems to be a quality product. I will say I am happy with XDP and have zero complaints or concerns regarding them. They get a 5/5, this muffler on the other hand is lucky to get a 2/5. Order # 1762150

The muffler is NOT quite as advertised, it is advertised if quite yet the moan / drone / loudness in the cab is much much more than the advertisement states.
Great muffler when pulling heavy. Get rid of the drone noise.

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.

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?
View Staff Answer 
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?
View Staff Answer 
Answer
Yes, the MBRP Universal 4" Quiet Tone Mufflers have a 24" body, 30" overall length, and are 6" diameter.
