Currently I have a set of Flowmaster 40's on a 3 inch exhaust and was wondering if there was a better muffler with regards to flow and sound. Yes my do drone (which in Hawaii and short distances not an issue - here on the mainland starting to become and issue....thanks in advance

My 340 Cuda has the Flowmaster 40's with 2½ inch pipes. They do drone, but I don't mind it because otherwise I love the sound of them.

Try the Dynomax Ultraflow. Your gonna hear it though.

If you do a search you will find about 30 posts on this subject, each with about 10 different opinions on what muffler sounds the best. Eliminating drone is one of the most difficult issues with exhaust systems, because a muffler that works on one car may sound totally different on another car, even with what appears to be the same setups. People also don't agree if the drone comes through the side of the pipes, the body of the mufflers, or out the tailpipes. Mounting hangers can also change the tone of the exhaust.

if you have the room, dynomax 17769 large body "hemi" turbo mufflers, and then some glasspacks in the tailpipes as resonators to kill the drone....

if you don't want drone, look at the dynomax VT's
