Good afternoon,
Nearly done with engine work on '66. Starter replaced, new radiator, carburetor, etc. fixing brakes. Had a hangup with the radiator hoses due to lengths and diameter/fitment issues.
Should be running and roadworthy by the end of the week. I'll continue to work on small items like mirrors, headliner, etc. but in the meantime I'm really wanting to figure out exhaust.
I would really like the truck - a v8 352 - to sound like a nascar - deep rather than glass pack or raspy. Was considering Flowmast Super 10 but curious as to what you all think?
Right now, no muffler or pipes at all - cut off just behind cab...so I'm wondering what my options are etc.
An FE has a distinctive machine gun fire poppy sound. No getting around that... I have run through straight glass packs and had side exit on a 390 and it was obnoxious. 40 series flowmasters is about as loud but has a much deeper throaty sound. Add a crossover (h-pipe) to even out the exhaust pulses to smooth out some of the FE machine gun fire sound and pick your decibel level chambered muffler.
Flowmaster 10s on my 390 and no regrets. Initially had installed 40s but just wasn't a fan. Pipes exit behind rear wheel and no annoying drone, not even on long trips. https://www.ford-trucks.com/forums/1...l#post18872351
I have 40's with no crossover dumping in front of the rear wheels. Sounds awesome except for the cracks in the headers.
you hear that Santa? Cracked headers!
Do I have to have pipes go all the way back or can I just end right under cab? New to all this so from a loudness perspective wouldn't it be louder with less pipes?

The longer the pipe, the quieter it will be. Initially I had 40s ending just behind the cab. When I had exhaust redone, used same but extended to behind rear wheels. Way quieter, That was why I switched to the 10s. Disadvantage to short pipe is you hear more in the cab as well. If your plan is to keep the short pipe, I'd go with the 40s
My 69 long bed runs a 390 with 36 inch glass packs and full length pipes, exiting behind the rear wheels.
It was quiet enough, but did have a nice rumble around 1500 - 2000. Going down the road at highway speeds, it was very pleasant.
I think what you need to try and achieve is not what the thing sounds like to you sitting in the driver's seat, but what does it sound like to people standing beside the road. You don't want bystanders to look at each other and say, "damn that thing sounds like $^@*". Pipes out the back help, pipes out the side make it sound like a sick 4 cyl. to bystanders.
You would be surprised by the low authoritative rumble from this muffler as the installer was and he picked it. Exits behind the right rear tire as per stock. The truck doesn't give anything up to the 14" Magnaflows on the Cougar or the 20" Dynomax on the Polara. Heck even the 410 Parklane, with stock mufflers has a definite note when you are behind it telling you something big is inside. Flowmaster I avoid like the plague.
On all of my current fleet, and former fleet, I get the shortest glasspack which I think is either 12" or 16" tuck it up close to the engine 2.5" out to behind the rear tire and I've had a lot of compliments, loud enough when you romp on it, but mostly quiet and not annoying, had and have them on my 300's too.
My 77 F150 SB 4x I actually have the short resonator off an 08 Ford something my buddy had laying around from one of his friends new exhaust they swapped out, it really sounds good, from my experience having the muffler closer to the engine gives a little more "cackle" to it that I like.
