This 300 has big clifford 270 cam, 4bbl Holley on offenhauser c, headers into duel 2 1/4 pipe into a duel super 44 flow master into duel 2 1/4 tailpipes
It is loud and rude, there is no mistaking that it's a six. Click the picture

My "Y" pipe ends about 6" past the O2 sensor and it's got about 18" of 2" before going up to 2-1/4" into a Y then the Y exits as 2-1/4 and that goes all the way back into the stock tailpipe.
It sounds like a small (non-turbo) diesel tractor through the whole range, except at idle where it's pretty quiet or just off idle, where it sounds like a marine V8
Back before I finished it, it ended as a turn-down about about 2' past the transfer case. Now THAT was obnoxiously loud.

I have recently talked To a buddy of mine that's a 300 man through and through and works at a muffler shop and he said the way to make them sound like a cummins is a 3" complete straight pipe no mufflers no cats it will give it the growl of the cummins when your taking off and won't be to much cab drone if you run it all the way back to stock exit behind rear tire totally doing it to my 83

I had an 84 with a clifford intake, holley 2bbl, hedmans, and 2" true duals with turbo tubes....a small airplane taking off sounded very very similar...thinking back it sounded like sheeeit, but at the time it was the mid 90's and I was in high school and it sounded pretty rad lol.
Let it be noted my 86 will be nowhere near that obnoxiously ignorant lol...might even keep a stock looking 3" single...

I have to agree. I just rebuilt mine and ran a straight pipe with a Cat and it was still obnoxious at speed. Sounds like a loud tractor. Then I put a flowmaster 40 in and its pretty nice now.

I personally like the sound of the Hooker Aero-Chamber mufflers. They are a nice straight thru design. But they still drop the sound level just enough to keep it from being too obnoxious.

I own a 93 w 300 EFI. Not sure if exhaust manifold is original or not but has two exits with true dual pipes no mufflers. It had stacks but because im swapping cab and bed for an 85 removed them. No difference in exhaust note or sound. Sounds louder than my sons 24v cummins w sewer-pipe exhaust. If you're looking for that head turning diesel sound you're on the right track

Heres mine. stock 300. 2.5" exhaust to a 5" stack in the bed. It was just a test to see what 5" stacks would sound like. I really liked it. Sounds better in person when you're not in the cab.
Right now its about a 5' chunk of pipe just coming off the manifold ending at the back of the cab. Just enough to keep the heat off the starter till I build up funds.
