i just installed my flowmaster 40 series and i"m very disappointed not the type the sound the i wanted i previuos owned a 03 ram 1500 4.7 with the same type of mufler(40series flowmaster) it was nice tide rumble sound so i think with the same 40 series and bigger engine 5.4 i was expecting almost or better sound out my 5.4 engine and what i got is a very lousy sound i feel like i driving an old truck
any solutions?

 

These trucks arn't that easy to make sound real good. Simple as that. .

Get headers with new cats, and install two of the shortest Magnaflow or Flowmaster mufflers.

 

yea i like the sound but these trucks arnt going to sound like an old hot rod if thats what your looking for. Newer cars are starting to sound different than older ones. you can try taking out the cats or putting headers on
are you concerned with the performance or the sound?

 

I have a si/do 40 series dumped right out of the muffler and I really love the way it sounds. Maybe its not as loud becase we have something like 4 cats?

 

My Maggie SI/SO sounds great. I get thumbs up for folks left and right. Did you just do mufflers or cat-back system?

 

I got 2 under my truck.....did they change something mid production? I hear all this talk of 4 cats and I don't have but 2.

 

not just the muffler with short pipes rigth in front of the tire like Harley davidson
after complaining to the manager (friend of mine) he suggest to cut of the catalytic converter if i really want a loud sound which i not agree,,,hoo well i guess i going to stick with it

thanks guys!!:o

 

I believe they did. Mine had 4, but I removed 2.

I believe I remeber when we were crash testing these we were updating the exhausts at some point. They went from a 4 cat system that had 2 HEGO sensors between the manifolds and the front two cats, and then 2 more HEGO's between the upstream and downstream cats.

If I remember correctly the prototype exhausts we were updating to at the time (Late 2003) just had one very large cat that had the HEGO installed right into the center of it? Is this how your truck is Matt?

 

Oh and Omar, could you please try to use some punctuation?

To answer your question. I have a stainless Flowmaster Delta 50 with 2 of the 4 cats removed and I like the way it sounds; I get compliments very often.

My only complaint is w/ a lot of Flowmaster systems you get resonation in the cab which I do. I get some good resonation in the cab for about the last 500 rpm before the truck shifts, but on WOT or hard acceleration you can't beat the sound of a Flowmaster IMO.

 

I'm very sorry for the punctuation I'm working on my grammar English is my second language.

i will probably try that!
thanks!

 

I have 1 50 series and it sounds GREAT with my 4 inch tips!! I have a buddy that ran true duals with 40's and it doesn't sound good at all either to glass pack poppy sounding!

 

I have the 40 SiDo coming out the back and I love the way it sounds. would not change a thing.

 

that is the same way the Tuscany customs trucks are set up little louder than mine but sounds good

 

I have the 40 series, and have the same resonation, but I'm used to it now.

As far as sound and performance, I have no complaints. I don't get the loss of low end that everyone complains about and the sound is great. I'm very happy. I am thinking of headers, however.

 

Shoulda had it straight piped if you wanted it to sound mean. I had mine done at the muffler shop and he did a true dual from the cats back. It was the meanest sonofabiotch ever. Man, when id hammer it from about 20 when it shifted down you could feel the ground shake...i swear to god. But it was almost too loud so i got the magnaflow DI/DO muffler and LOVE IT.
