What's up fsb members. i drive a 96 eddie bauer bronco with the 5.8. right now i have dual exhaust with a glass pack muffler. a friend of mine is selling his flowmaster 40 series muffler, and i was wondering if it would be worth it to buy it and replace the glasspack with the flowmaster. i would like for the bronco to be louder, and deeper. would the flowmaster be a good choice? thanks:rockon

Using the clips on flowmaster's site is totally pointless because it's going to sound completely different on his truck. I think the only clip on there is with a 305 from a camaro or something...

Yeah, I've got a 40 series delta flow on my bronco, and it was a minor improvement over the glasspack... I wouldn't say it was louder, just got a deeper tone to it... but at the same time, the moron at the shop also put on a piece of 2" tubing out the back of the CC into the muffler... go figure... 2 1/2" from the manifolds, all the way back, and he puts a 2" on there... gonna have to cut that off and fix it soon.

Mine used to have two glass packs. I took them out and now it just has the first Cat, and then goes back and exit behind the rear tires out the sides, looks like they just copied the factory one and put it on the other side. Mine is a '92 though so your '96 might not act right with the same setup.
I am currentlly taking all the crap off and redoing the whole thing though, all stainless from the heads back, I can't wait to hear what that one sounds like.

My single 40 is loud as hell, no cats and a 60 degree turndown in front of axle..
Maybe 10.5:1 and 408" has something to do with it :toothless

Any drone or interior resonance with the 40 series Flowmaster? My glasspack (installed by previous owner) drones something awful at highway speeds. The volume, surprisingly, isn't too loud or ratty sounding, though. I'm going to replace it, but haven't decided on what.

Yeah there is some interior noise, but for me it is not too bad until I get past about 70 mph, the exhaust is loud but the wind coming through the vent windows is louder.

I don't notice the drone as much, but that's mostly because I put sound proofing material down. Before I did that, it was definitely noticable, but not obnoxious.

i ru n dual Flowmaster 40s using headman long headers, 2.5" tube, X crossed and no cat. my exhaust ends just before the gas tank.

It is loud enought to trigger all my neighbors car alarms just barely touching the gas pedal, and people pretty much hate my for that....

Final exhaust will come from engine displacement, compression, camshaft profile, header type, tube type, and so on. I have seen cars with similar exhaust as minem but ending all the way to the rear bumper, and they are quieter.. I also have seen folks running a glasspack before the flowmaster, and they are very quiet...quiet as a magnaflow, but still with the deep sound of the flomaster. (glasspacks tend to block the high frequency pulses, flowmasters tend to block the low frequency pulses, so ends up like a "bandpass" filter)..fitting a system like this may be hard on a bronc b/c of the short wheelbase

for us without cats, the best exhaust finish is just before the rear wheel, so u can wheel with the rear window open (and not choke on the fumes).

I used to have tips facing down to the ground, but my bronc looked like a street sweeper whenever i ran in to find dust, the exhaust would blow it off the ground creating a small cloud.

finally, in cab resonation will vary (also mufflers get hot, so u better have a decent heat shield above exhaust or rear set passenger floor will get very warm, factory works ok). In my case, biggest resonation occurs at around 2k rpms...since i have no OD, Highway cruising is not so bad, since engine is above the 2k rpm range..
