Ernie,

The Lite-Jett mufflers are available for the 40L, 46,50,60,65 and 76L. Its a very light weight, untuned muffler. Since the engines that use it tend to turn lower rpm, it tends to be somewhat quiet too. Right now Dub offers 3 sizes - "40", "60", and "76"

For the 3D and some scale appliations, you really do not want the 'pipe' effect coming on line between midrange and full power. The lite-jett muffler presents no issue there. You get a smooth throttle, and excellent fuel delivery.

In the case of the 76L, the purpose of this engine design was to provide power via displacement, rather than with the tuned exhaust. So although it does benifit from using the Turbo-Jett muffler (broad range tuned muffler), it does not fully benifit from the Jett-Stream tuned muffler (a bit more speficically tuned).

For my 76L installed in the "40" sized Edge, the turbo-jett worked out perfect for both performance and in the installation. For applications such as the profiles and such, the lite muffler is prefered since it provides the lightest weight and most compact engine installation.

Looks like Autoguns is doing well here. The tach numbers are right on the money. Thanks for the photos JW.

(note, in photos, the smaller muffler labled "40" is the .25-.40L size version)
