“After a long summer of ‘drone,’ fall is the perfect time to replace your loud performance muffler with a drone-free DynoMax VT muffler or one of our rich, throaty Ultra Flo mufflers,” says Chris Gauss, director of performance products for Tenneco.

This is a discussion on Dynomax Muffler option within the Engine & Performance forums, part of the 4th Gen : 2009 - Present category!
You can also listen to sound bites of most Dynomax mufflers (though the VT sample is not yet posted) on the company website at . We haven’t yet heard the VT mufflers firsthand, but we’re curious to know how well they perform, so any input from folks who bought them would be welcome.
Another hot tip: Use quality hangers that will flex with the body and frame of the vehicle. We broke at the least five of the cheapo exhaust hangers purchased at the local auto parts store. After the installation of the Dynomax VT muffler our decibel meter recorded a full-throttle level of 92 dB and a cruising level at 65 mph of 86 dB. This was a noticeable decrease of cabin drone inside the Jeep.
