This is how a 2011 Dodge Ram 1500 Crew with the 5.7L 390 HP Hemi sounds after I swapped the stock 26" monster muffler for the new DynoMax VT muffler. It is the 22" 3'" Single In / 2.5" Dual Out model # 17963. This muffler has what DynoMax calls "Valve Technology" which is pretty quiet when at idle or at highway speeds, but opens up at wide open throttle. It is really an improvement over the stock muffler, but has the advantage of Zero Drone at Highway Speeds. At the time of this video, the muffler has only been on the truck 24 Hours, and about 40 Miles. It should get a little louder with time after burn-in.

Mustang Exhaust Shoot-Out - Dynomax VT vs. Flowmaster 40 Series Mufflers
This video compares five Exhaust
set-ups on my 1966 Ford Mustang, including open Exhaust, Dynomax VT mufflers with/without
tailpipes, and Flowmaster 40 Series mufflers with/without tailpipes. The
car has a stroked 302 with 10.2:1 compression, a solid roller cam, and
aluminum heads. This car is a weekend driver, not a daily driver. I've been
struggling to decide which mufflers sound best, so I welcome your honest
Dynomax Ultra Flo vs Walker Muffler Comparison - sound levels and sounds!
We've compared two mufflers in search of quiet(er) performance.
*EDIT* Dyno results
are in! 443 rwhp and 490 rwtq. Taking into account the 1.5 degrees of
timing we added, the mufflers cost NO power. Before we made 422 rwhp and
