There are other things to consider other than sound out the back. Noise transmitted to the cab is greater with some mufflers. For example, a Flowmaster 40 generates more cab noise than a 50 series. Tone, as opposed to the noise of straight pipes, is a function of the silencing method. If you look through the inlet of a Flowmaster you will see metal indicating a baffle design. If you look through the inlet of a Magnaflow and some other popular makes, you will see out the outlet, indicating a straight-through design. I always put my mufflers as far back under the bed as I can since I prefer to hear my music, not my exhaust.

I'd like to hear what the 4.0 sounds like using the same muffler as RajunCajun has without the other mods.

I'm very glad to see guys here who use other brands.

Is there a way to check which series of flowmasters i have w/o asking the person who done it? I dont think it's written on the muffler itself but i could be wrong. Sorry if it's a dumb questoin, but im just curious.

i'm not sure how to check but i'd be almost positive you have the 40 series. their the most popular it seems especially for our 4 and 6 bangers. if you had a 350 or a 400ci with big horses you may have a 50 or 60 series. you could also go to flowmaster.com and compare yours to what they have pics of. there are visual differences between all of the series.

i have a good mechanic friend of mine who said there is a flowmaster muffler with dual in and dual outlets so as to only run one muffler. he said it would be fine with the 3.0 and i really don't need dual mufflers but will still have the dual exhaust look i'm craving. however, gm did this sort of thing with camaros, t/a's and the grand nationals and was told once that design was very restrictive and i would imagine it would be for my ranger also? i know i may be comparing apples to oranges but i'm looking to get a little performance out of this and exhaust is the first place i'm starting as far as power mods are concerned.

frd, this is my newbie opinion that i get from reading. To get the best performance you need a total exaust system. I think someone said that replacing things after that cat will only give a good sound. Although with that being said, someone posted on the first page, the dynamax muffler gave them more "*****" for towing. I think the stock is restrictive on the 3.0's but perhaps only after about 3k rpms. I found my truck's intake was restrictive after ~3k rpms after i put a new intake on it. The sucker has noticably more power after 3k rpms. I dont know if the same goes for exaust. Im sure it must affect it. I just think that from a little 3.0 one pipe splitting into two wouldnt make that much of a big deal. Ah well, im just rambling off here i guess. Dont take anything i say for a fact lol. Just thinking out loud.

i forgot something else that was explained to me. unless i was to change the existing cat. and maybe go with some headers, mufflers only wouldn't do much but make some better noise! i guess a "true dual exhaust" system would be what i'd need for some extra horses. i believe it would help the mpg. also. i also heard that the k&n intake doesn't help much but now i'm wondering. the combination of the two is key. thats what i'm understanding. please correct me if i'm wrong.
