Ordered the MBRP 4in turbo back for my 99 7.3 and realized that my neighbors were going to hate me since I leave for work so early. Ordered this and honestly it’s super quiet, it could be slightly louder. I’m still happy with it. Don’t have gauges so I have no clue what it did to my EGT’s, really hope it didn’t put me back at stock.

MBRP Quiet Tone 30" Muffler. I have no idea why its called "quiet tone muffler". 10 being straight pipe loud and 1 being all you hear is the engine, I would give this a 7. I put this on a 14 Cummins with 4" exhaust. I got this muffler because I wanted to get rid of the drone in the cab. When I received the muffler I was assured that it would get rid of the drone. Well, it didn't. It did cut some of the noise down. But by no means is this a quiet muffler. All it is, is one giant glass pack. At 1,500 rpm I still have a good amount of drone in the cab. Drives me nuts! All you hear is exhaust. I gave this a 3 out of 5 stars because of fast shipping and a strong quality product. Don't get me wrong, this muffler is very nice but should not be called quiet tone. Last, WAY over priced! This is a $75-muffler. Not a $140- muffler. Way over rated product!

Installed on a duramax that has a 4” mbrp exhaust system with a blown out steel pack. Not much quieter than the steel pack has more of a rumble now.

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?
