Just purchased a 2000 Durango and thinking of changing the muffler, would a Flowmaster series 40 muffler be too loud internally.

The 40 series is very loud and you will hear it in the cab. Sorry.

Any recommendations, also should I stay with aa signal outlet or change to a dual outlet?

Hey, I have the 40 series in on my 04 Hemi Ram and it sounds so BURLY, you can hear it in the cab but not too bad... at first you will be like HOLY SMOKES did they put the exhaust in my cab... but you get used to it... I wouldn't have it any other way, I love the sound of my truck.


buy it.

Here goes, if it has a V8 then it needs Flowmasters. If you want it quieter, then just buy a 50 series instead of the 40 series and it will be quieter.[sm=smiley2.gif]
