Hey guys I just installed the flowmaster 50series DOR on my ram with the 4.7 V8. I have had it on for about 3 weeks now and I like it a TON more than the stock. It has also picked up my mileage too as I am going to get about 400 miles on this tank with a miscalibrated spedometer and mostly all city driving.I am also going to be putting headers, CAI, and free flowing magnaflow cats on it in the near future.Anyways like any guy I like the sound, but it could always be louder. I have a few questions to ask...
[ol][*]How much louder is the origanal 40 series muffler vs. the 50 series performance SUV/Truck?[*]How much more interior resonance will I experience? (will I be able to carry on a conversation at 60+ mph?)[*]Will I lose any mileage or performance that I gained from the 50 series?[*]Also if you have the 40 would you recommend or use it again?[*]Any sound bits of a 40 series that are in the cab while driving?[*]Would I see any performance gains after doing the mods and having the 40 on their or would I be better suited to just pony up and by a magnaflow 5x8 muffler when I get the free flow cats?[*]How loud would the magnaflow be compared to the other two?[/ol]
Thanks for your help,
-Eric

 

Just asking but did you look at the exhaust link at the top of the page?

 

i like my 50 hd series

 

I have a 40 series and for me it's a little loud at times in the cab as in you can still hear it with the radio on unless you crank the volume up. Honestly I'm not sure what I had before a shop thought it was a 40 series and it measures the same dimensions Sumimt Racing gives for the 40 series but it was a lot quieter inside the truck but almost maybe not quite but almost as loud outside. It sound amazing outside and good but quiet inside. I loved it. I wish they put what series they were on the actual muffler. I wanted the same muffler again so I got the 40 series and it's a little loud at times inside and doesn't sound much louder maybe a little outside just a lot louder inside. I can still carry on a conversation just fine but you can definately hear the exhaust inside the truck. I'd still recommend it and most of the time it is fine it's just sometimes I wish it wasn't as loud.

 

How would the 50 series HD sound on a o3 Hemi????

 

I've heard really good and one guy on a dirtbike forum I'm on seems to really recommend that muffler for a Hemi Ram.
