I'm in the position now to make my 83 F-150 with the 300 sound a little better. Right now its too quiet for my tastes. I don't want it droning in the cab if i can help it. I just want something with a decent sound as i pull through the revs. Anything i can walk into the local autozoo or orielys and pick up? The truck is stock otherwise for now. I just want a little noise.

Suggestions are very welcomed. .

 

really i am not positive on what muffler to go with...magnaflow may sound good...flow 40's...i hear it is better to stick with single exhaust....2.5"...if dual, put an x pipe in...cats can help reduce ricer sound...if anything, slap on a high-flow cat...the further away you put the muffler from the engine, the deeper sound...this is the best advice i can give you...there are many threads in this forum about exhaust...here is one good thread that may help you out

.......in regards of sound.
My 92' E series with same power plant as yours.
I began with 3:08 gears,4OD,30" tall tires.
I removed all exhaust--from engine to rear tail pipe bracket. Installed new split manifolds, installed 2.5" pipes down to where the cats would normally be----eliminated both of them----joined the two-2.5" pipes into one, installed a stock 18" generic muffler( the same type most muffler shops carry--probably a Walker brand) which had one inlet of 2.5" and one outlet of 2.5". Installed the muffler ahead of the rear end and ran the tailpipe -2.5"- out and in front of the rear wheel.
The van gets excellent gas mileage, has a good sound, breathes well and will run past the total on the speedometer on level.

Mine has a total 8' of 3" Pipes w/ Flowmaster 40's hung just prior to the rear axl, the the rest of that 8' of pipe run up over the axl to the rear bumper, then turns down hidden by the bumper.
The wife likes the way the "Olde Girl" sounds & for the most part I do to, though a tick loader in the cab then I'd wish.

 

the thing you need to keep in the back of your mind is the 300s exhaust tone can be as loud as a v8 but it will NEVER sound like a v8. if you want a powerfull tone cut you exhaust off at the downpipe and straight pipe it, if its to loud for ya get the longest glasspack you can find and section it in before the rear axle, the sound will be the same only mellow and quieter. on my 82 f100 im running 2 1/2 inch straight pipe it has a mean rumble of the line and has a noticeable tone durning accel. and is almost quite while crusing. I ve tride many turbo mufflers and two differnt flowmasters, nothing like crawling out from under the truck only to start it and instant honda. one other thing i can tell ya is, if you run a single or duel tail pipe it sounds better then just dumping the exhaust under the truck, the tail pipe helps to rid you of the my muffler fell of nosie youll get with dumping it out under the truck. one last thing try to stay away from true duels with the 300 like someones said before it sounds like two crotch rockets runing circles around each other. i love my 300 i know it will never sound as good as my 302 but it'll last longer

 

Well there must be Some Difference in Running Duell 2 1/2" pipes into Flowmaster's & Running Duell 3" pipes into Flowmaster 40's, because My 300+c.i.er sounds Neither like a Ricer Car, Nor a Ricer Motorcyle!!!!!

 

i can cruise and not hear the engine running in the cab. 3" stright pipe. But it is LOUD anyother time, idle, accel, decel, crusing if i put a tad more throttle.

makes thoses Small Blocks sound quiet. well except for emily's 65 fastback, but that things runnin 450 horse on a 302....so ya.

but my 600 horse 351 ranger is louder than her mustang.

my inline is the best sounding, i think.

My original plan was to put Flows under the truck. But someone stole the mufflers before i could put them under the truck. I don't quite want straight pipe loud. I just want some noise to let me know the engine is still running. This thing is so smooth and quiet the only way i can tell its running is either watching the Tach or feeling the shifter vibrate at idle.

Thanks for the suggestions ya'll. I appreciate it, keep em coming!

 

so you're saying you cut the muffler and cats off and ran a straight pipe from your exhaust manifolds? I'm really confused, sorry. Not trying to steal this guys thread, but I'm wanting to put dual flow 40's on my truck (straight 300), and I don't want it to sound like the lil "race car" hondas that run around town.

 

natedog, sorry for the confusion i'll try to make this simple. i cut the factory down pipe off right were it bends under the front of the cab, so all thats left of the factory system is the manifold and about 3 foot of downpipe. the factory downpipe is a 2 1/4 inch pipe. my new pipe is about 8 foot of 2 1/2 inch pipe that i slid over the down pipe about 6 inches and welded it up. i had a buddy of mine put a bend in the pipe so it exits the side of the truck before the right rear tire. thats pretty much it very plain and simple and pretty cool sounding to. also if your one of the lucky ones like me thats blessed with a non emission testing state then by all means get rid of the cat, you'll increase your sound and gas mileage. you mentioned dual flow 40's, if their any thing like plain jane 40 series they'll give you an ok sound durning accel, and crusining but mine sounded like a lawn mower at idle. i dont even wanna think about how much money was spent on at least 25 differnt exhaust setups for my truck. but the good old stainless steel 15 dollar fence post as i call it sounds the best by far.

and mr col flashman ive followed your engine build up and ive downloaded your exhaust video clip and i must say your truck sounds pretty good. but since your engine is not exactlly stock and since your running headers im sure that helps with your sound. also are you running cats or any type of ''x'' or ''h'' pipe ?

 

J.B

Just "Colonel Flashman", the same as in my signature, no "Mr." needed.
Thank'ee, It's tick Loader in the cab & not as Throaty as I hoped for, but that can be remedied when these wear out & are replaced.
And that's a Negative on Any of that exhauste crap you've mentioned, as Neither my year model of truck ('58), Nor my year model of engine ('65-'72 series), requires it.
Technically I'm running a Header, ablbeit a split one, but who's splitting headers, splitting hairs?
And what's the sense of an "X" or an "H'" pipe if I wish to run a True Duell Exhauste System, don't both of those items defeat the purpass, porpose, platipuss........?

 

It really helps in the decision making process when Summt Racing is right down the street from your house, I bought the Summit cat back 3" single system. I think it was about $200 and the install was very clean and easy. My review is as follows: Mellow, Not too loud, and not too quiet. 'nuf said.

 

go buy efi manifolds, have 2 downpipes, run a 2 1/4 true dual, no x pipe no h pipe. this is a completely different sound than an inline six. it sounds like a mixture of a big v6 and a small v8 but not exactly like either. thats my 2 cents.

 

On a stock carbed 300 I'm running a single 2 1/4 pipe through two gutted cats back to just before the rear axle where it goes into a single offset inlet, dual outlet flowmaster 40 which dumps about 4" past the axle tube.

At idle it's nearly silent, at a high idle it has a nice little thump to it, it sounds like a muffled diesel under WOT, and has a slight drone to it at cruise, but it's quieter than the road/wind noise at 70 mph. I can still listen to the radio no problem.

I've had two people (both ford guys) mistake it for a mildly built 400 running a full exhaust.

i have ran a variety of set ups on my truck...

flow 40 DF with duals - quiet, sounded kinda ricey and no power gain

flow 40 DF exiting in front of rear tires w/ bit tip - better but still ricey and no power gain, resonated

flow 40 DF dumped - best sound, resonated in cab terrible, no power gain

18" long glasspack exiting in front of rear tires - ricey, ricey ricey. no power gain...

18" long glass pack only - ricey but good at idle, no power gain

2 feet of pipe off the first cat - getting better, more tractor like and very loud. rattle the cab to much

2 feet of pipe off the first cat into a 45* exiting in front of rear tire (current set up) - my favorite...loud as hell but has a distinct sound...resonates inside but barely.

i have soundclips on my superford site, if ur intertested PM me and ill send teh link.

have a few friends w/ magnaflows and they seem to sound good. i have a SI/DO magnaflow small case muffler here im debating to put on before i get my full exhaust done...if i do ill get some sound clips.
