So - I like the sound of the Dynomax race bullet mufflers - are these a straight, easy swap out anyone done this on your Durango...? You tube has a bunch of vids on Fords but no Durango

 

Havent heard of anyone using em on the Rango!

 

I bet they'll sound great, though your concern should be introducing an interior drone (been there, done that on my g2 so have so far left my G3 alone). Depends on where you put them and what you remove. If you replace the resonators and leave the main mufflers, then you may be OK. If you replace the main mufflers and leave the factory resonators, you could be OK. If those would be the only mufflers, there is a good chance you'll introduce an annoying drone that womenfolk seem more annoyed with.
