Still putting together my list, what do you'll think of Flowmaster mufflers? Which out of the many out there would you choose and why?

I have always like the Flowmast mufflers. Their 40 series mufflers have always had a great sound for V6 and V8. I also like the Dynomax ultraflow's for V6's, it has a nice agressive sound. I thought about these two for along time and went with Flowmaster.

i have done a search on Flowmasters website.... which of their mufflers works for the R/T...

I believe some of the v6 magnum/charger guys are also going with the 40 series. Some said it was a little too loud but I think that may be more of a significant others opinion than their own. ;)

As I said somewhere else.....give them some earplugs for Christmas...lol

I agree earplugs for christmas... I had an 04 Chevy Tahoe Z71 before my Avenger and it had Flowmasters on it... The sound was like music to my ears... Is there any HP lost/gain or MPG gain/lost with these mufflers?

in the flowmaster website they say you will gain a little hp.. it doesnt say how much though..

Not much with just a muffler. Here is a dyno chart from Magnaflow with a Chrysler PT 2.4L
