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
Magnaflow 18" Muffler on a Hemi
This is a 2011 Ram R/T with an aFe Stage 2. I removed the stock Y Pipe and
replaced it with a Magnaflow Y Pipe and I moved the Y Pipe all the way next
to the muffler. The muffler is an 18" one in and two out.
