exhaust que.
I've posted a similar post a while back (https://www.ford-trucks.com/forums/6...fler-help.html) but I have my new truck so I need new information.
I recently purchased a gas F250 5.4L triton v8 super duty FX4 and i love it! I need only to customized the exhaust system like all my previous trucks for it to be complete.
I've come into a rut.
On my:
+1997 150 i had a cherrybomb glasspack muffler with imitation dual pipes with 1 cat. converter
+2003 150 i had straight pipes with imitation dual pipes with 3 cat. converters
+2003 F250 i have stock muffler and i think 3 cats as well.
I've called 3-4 autobody/exhaust shops and asked if straight pipes or a cherry bomb glass pack muffler would be louder...and it's been known that autoshops will lie to you for several reasons (to buy their own product/version, or to cut back on noise.). I'm "not" too concerned about performance or backpressure. I "only" want to know which will give me the louder sound.
Hopefully someone can help and be honest as possible. Here is the question in short:
"Which will work better, straight pipes or a cherrybomb glass pack muffler???"

Well youve contradicted yourself...you say you only care about noise, and then you ask which works better...
For pure noise with no consideration to tone, cut off your exhaustafter the Y pipe.
Now if acoustics matter then straight pipes will give you more resonance.
A glass pack will be loud also and if you want the most noise then run it hard for 3 weeks take them off and shove a hose down to blow out all the packing and it is then an empty shell (straight piped) axcept that it will pass a visual muffler inspection if the blue lights in your area dont like the noise.
Do you have emissions inspections in your area? if not i would sujest cutting it off befor ethe cats and drive it for awhile to see if you like it, then if its too loud you can add a system w/ glasspacks. Its easier to build from cutoffs if they are too loud than to change a full system if it is to quiet

thanks for your reply but i think you and i have confused each other.
yes, i care about the noise to the point that i dont go to jail b/c it's toooo loud. So that's why im asking for opinion which is better to have. a straight pipe setup or a glasspack setup? i've never had a 250 so I Dont Know the right answers.
I havent done anything to the new 250 so its stock everything. Here's a cheap paint example.
This is the ideal setup of either straight or cherry

Well unfortunantly i cant tell you which you will like better because what is too loud or not to loud is definantly an opinion thing.
I CAN however tell you which i would do.
Because your engine is a modular engine, it has a mellower exhaust note (thats just the way it is) so i would sujest going with a full straight pipe system to gain the noise you want.
It appears that you dont want to run a true duel setup is that correct? and are you planing on this being a catback system or are you going from the heads back?
Personaly, if i had that truck and has to pass emissions i would run short tube headers through high flow cats (i hate cats) into a true duel through an H pipe but it aint my truck...
Slick drawings by the way

Hmm, you have an excellent point. I think it'd be easier to just put in straight pipe, imitation dual, and go with that, first. If that doesn't work then I already have the pipes there and i can just have a 2-3 foot section to fit a cherry bomb wouldn't be too terrible. however, if the reverse would be financially efficient, that might work too. That's, I guess, a personal fix.

Beware, Cherry Bombs are restrictive. Check out this link where the guy cut some open and found out: http://www.greenfries.info/Resonator.htm
Maybe Flowtech Red Hots (similar to Cherry Bombs) would be more open. Have to look through them to know for sure.

Thats why you blow out the glasspacks like i described abouve. And they are still one of the better flowing mufflers that ive seen.

As far as using any other glass pack-type mufflers, I've heard to use i think dynotec/dynomax (or something) bullets, purple hornies (dont ask...), and then gibson mufflers and plenty of other suggestions, too many for my taste. I've always used CB glasspacks and i 'know' how they are and i love their sound b/c its not too loud nor too dull/quite.
I'm not automotively inclined too well so I have no idea what you're getting at in terms of cherrys being restrictive. "IF" i read you right, cherrys are quite when first put on b/c of the fiberglass packing (the restrictive part you're referring to); however after "blown out" (in my definition, driving fast and hard for a month or two) then they become loud as crap or hollowed out as desired???

The restrictive part is the smaller tube inside the glasspack. The outside might be 2.5" (or whatever size), but the GP will narrow down inside to less, and that hurts flow. Lots of "turbo mufflers" do the same thing. Thats why you research before you buy.
lordofdavipers- Almost all glasspacks start out quiet. They all burn in and become louder as they are used. Use what you like for sound, but there are better flowing mufflers out there. But using an antiquated muffler like a glasspack on a modern truck is strange, IMO.

The cheesegrater design of the metal does create some backpressure over a straight pipe, however the way the airflow is changed aids in the scavaging of the gasses from the muffler back, effectively undoing the damage from the backpressure created.

Thanks for your reply and handy information. That puts GP's into perspective. What stands out to me is your comment about older mufflers on newer trucks...that shouldn't be a concern should it?

Right, it's not just the cheese grater. The tube is smaller ID than the inlet piping.
Yeah, look down a Thrush Turbo and you'll see it gets smaller ID inside. My Flowtech Raptor is full ID all the way through. (Flowtech also makes the Purple Hornies mentioned above).
J.C. Whitney makes a dual exhaust with small Cherry Bomb type mufflers at the tailpipes. Don't know if any good.
I really like the sound of my Raptor, with the side exit in front of the tire. Deep bass sound.
Nice newer truck, spend some money for a stainless steel muffler that will last the life of the exhaust system. Holley I think makes some pretty good mufflers, like the Aerochamber mentioned in my link.
