Darts First Test Drive.
Mufflers is a tough one. A muffler that sounds great on one car sound horrible on another.
I love the Dynomax Ultra Flo on my Barracuda. So put some on my fox body and they sounded terrible. So swapped on Dynomax Super Turbos on the fox body which turned out great.
With 340 manifolds 2 1/4 outlet going into 2 1/2 TTI head pipes, I ran that combo once, something like a Dynomax Super Turbo should get rid of drone.
