I think it's about time for a muffler swap on the stang, but I'm having some trouble making up my mind. I am sure that I want that famous "flowmaster sound" but can't decide between the 40 series two chambers and the Delta flow two chambers. I've got a freind with the 40 series mufflers and that thing shakes the ground with fury (heart beats faster just thinking about it). On the downside, there is noticeable interior resonance. I was thinking that the delta flows would remedy this problem, but I don't want to sacrafice the quality of the sound on the outside. My car is already too quiet and I want to make a big improvment noise quantity and quality without becoming a public nuisance. Have any of you guys heard the delta flow 2 chambers? How do the two compare?

Any insight would be appreciated. Thanks!
