I thought I’d do a comparison of mufflers to share with you peoples. This is between a HUSHPOWER and MBRP muffler.
Done on my wifes truck, a 2007 QC 2500 which is complete stock except for a CAI with the catalytic and resonator removed.
The MBRP was installed on her truck a couple days after we brought it home. Since the muffler is a straight through design it’s pretty loud out of the box. At highway speed, it’s a great muffler and you can barely hear the truck. At idle or lower rpm’s though… it’s very loud. The best I can describe it would be blaaaaaaaaaaaaa. There’s also a good amount of drone at slower speeds.
Thanks to Richard at Hushpower, I was sent a muffler to try out. They claim it to be quieter and that it adds power. Danville performance ran one on their dyno and found they gained 13hp/33tq just by replacing the muffler. They tried first with a 4” and then found that by installing 4” reducers into a 5” muffler, they were able to gain the hp/tq and also quiet it down.
I’m still working on seeing if any mileage was gained by the Hushpower muffler but, I have found it to be a quieter muffler than the MBRP. It has a deeper tone and sounds muffled compared to the MBRP. That was music to my wifes ears.
The Hushpower is made from aluminized steel on the outside with T409 SS inside. The mesh inside the muffler is cone shaped at both ends. The holes are fairly large so I don't believe there's a need to worry about them clogging. The reducers have to be welded on which made the muffler 36” long…..the perfect length to replace the stock muffler. It weighs 20lbs
My wife is very anal about her truck and would tell me to get rid of anything causing it to not be the quiet comfortable ride it can be.
The results from this comparison showed us the HUSHPOWER muffler does what it claims as far as how it sounds. Danville performance has built some sweet trucks so I'm inclined to believe their dyno results.
Here’s a video I made of the 2 mufflers installed. It’s a little hard to tell a difference in sound but, you can notice the muffled sound the Hushpower has compared to the MBRP.

Rip had told me a couple years ago, that at around 610-625hp, he lost 10hp going from a 5" straight pipe, to a 4" with muffler...but it was well worth the noise reduction.
