Making your V6 truck sound the best
A comparison of my old *Flowmaster Single chamber race series mufflers* and my current *Flowmaster OUTLAW mufflers*. The video doesn't do complete justice for either, around 3 1/2-4 RPM and above the Race series got very raspy and high (sounding more like a V6). The OUTLAWS keep their tone very well at even 4-5 RPM and have an awesome sound. The race series rumbled much different at idle and 2-3 RPM has a smooth tone, but after that sounded a little to raspy and got high pitched. The OUTLAWS all around sound fantastic and probably the most close your going to get to a V8.
