Picked up another 50 Shoebox Balanced and blueprinted flathead V8 Have one question, it’s very quiet How do you get that flathead rumble sound?
Fantastic automobile you did good. In the old days we would slap some glasspac Smittys on, you can find the same sounding mufflers today Enjoy the ride.
Thank you! Will those will give it that rumble th st I am looking for? It has single exhaust right now and you can’t even hear it running it is so quiet
Duals are the way to get the sound your looking for, check out some on line catalogs for ideas and $$.
Porter glasspack dual mufflers with 1.75" exhaust. Flatheads don't like big pipes! That's a super nice car!
If there wasn't anything more done than a Balance and Blueprint to a stock rebuild, I doubt you'll get the rumble sound you're after by just changing a muffler.
Customer with stockish flathead just put 2"straight pipes all the way back and it sounds great!not overly loud, sounds perfect to me and I've got 12"glasspacks on mine and it's a little too quiet.
That’s what my father in law was saying. He said I could run it with no exhaust and drive right passed a cop that I needed to do something to it
Little Truckdoctor has a 51 with a flathead and single exhaust. It has a single glass pack and it is very quiet at idle, but has a little tone when he revs it up.
Glass pack or steel pack straight thru mufflers. Cherry Bomb , Porter are good brands, get about 20 in. for medium sound 10 in for loud.
Straight pipes or smittys. 1 3/4" pipes. Too big and they sound like a fat lady farting on a pier in the dense night fog.
Duals and STRAIGHT PIPES (NO mufflers!) For goodness sake man, you live in Tenersee !!!. Home of the good-ole-boys.. Seriously..it should be quiet enough for a normal conversation inside the car with the pipes going all the way to the back bumper. For a little more 'sound' let the pipes stop under the car just in front of the rear axle. 6sally6
I went with 1.75” and Porter Muffler's. after running the car for a few months I pulled the intake a blocked the exhaust cross overs with some aluminum plugs I made. I found after doing that the excuse got a different tune bit more of a POP to it.
I've got an aluminized dual setup that was on my shoebox - free to anyone that wants to pick it up in western ma
I just saw a video on YouTube saying dual exhaust and he said it might take me a minute because I have the crossovers blocked. That wouldn’t be you? Or is it a popular thing to do?
It's probably worth what I'm selling it for lol - cut it a little more than I thought - this is it from the trans cross member back - it was a flathead with econo headers it obviously crossed under the trans then back over - car had 2" blocks and everything cleared - it did not use the "hole" in the rear cross member - they went alongside the kick up - don't know what the mufflers are, but it actually sounded pretty good Have a '65-'66 mustang 8" behind the shed too, makes a good swap Time for a scrap run!
This is my problem, my Shoebox is bone stock and whisper quiet. I need to make it to where I can hear it so I don’t kill it leaving an intersection.
Yeah I love the sound of a flathead. It is like a Harley shovelhead they have their own sound that can’t be matched.
