The Ford Barn

cuzncletus · 10-18-2011, 05:44 PM

Next up, since we're running with my new 8ba engine in the car now, is an exhaust system. The 39 frame is stock except for the crossover where the T-5 sits. (Anybody need the stock one?) I'm looking at Van Pelt's mellowtone mufflers. Anybody have any experience in what fits/sounds good? This is a built 270 in. flattie with a lopey idle.

Brockman's in Hagerstown Indiana make a good custom muffler. You specify inlet dia, outlet dia., case length and fiberglas or steel packing. A good USA-made durable product. Several 'Barners use them, I believe.

I run steel packed Brockman Mellow-Tones in all our modified (Red's Headers)Flatheads, I love the sound. Vic

Alot of guys are raving about the Porter mufflers. Go on line and check them out. There is a video on the sound of them. I have a pair on my blowen flathead in my 34 three window.

I have about the same engines in my '40 coupe and PU.
I run straight pipes.
They sound beeyootiful!
I was worried about them being too loud, but they aren't.
Sound great. Ken CT talked me into it.

My 46 Firetruck had straight pipes.....real long ones too. Sounded very cool!!!!!!!!!!!!!!

Ross in East Texas · 10-19-2011, 08:46 AM

What diameter pipes do you recommend if running straights? 1 3/4" or 2" Or other?

Bob G/Spanaway · 10-19-2011, 08:54 AM

1 3/4" gives the best sound.

So, if I understand you correctly, you aren't running any mufflers, Smithys, Brockman, stock....... you are just running straight exhaust pipes all the way back from the exhaust manifold or headers to the tail pipe?

I ask this because I was planning on a set of short Brockmans for the 39 pickup but if staight pipes sound good than I'm interested.

What effect do 2" pipes have on the exhaust sound over the 1 3/4"? I need to know the best set up for that sweet flathead exhaust sound.

46fatford · 10-19-2011, 09:06 AM

The 2" pipes won't crackle as much as the 1 3/4" pipes. The smaller pipes will give you that classic flatty sound.

Guys - I would think that pipe diameter is only part of the equation ie bore size (cubic inches), valve size and cam specs, compression ratio, carburation, header type, exhaust routing etc. I am running 2" straight and have modified all of the above so would imagne that what I hear singing out the rear may not be what someone else would hear in their application!

Bob G/Spanaway · 10-19-2011, 11:28 AM

I think cam and headers make a difference in the sound.
I have a '40 coupe with 245" and a mild 3/4 cam and headers, Edmunds heads and intake.
The 1 3/4" straight pipes really crackle.
Also '40 PU with 250" stock cam and exhaust manifolds, Offy heads and Fenton intake.
1 3/4" pipes and this one is noticably quieter than the coupe.
Still has a nice crackle and sounds great.
I was worried about them being too noisy, but not so.
They're a LOT quieter than most Harleys.

rustythumb · 10-19-2011, 11:46 AM

i've read that smaller pipes cause the exhaust to flow faster,= high pitched sound & bigger pipes flow slower = deeper sound. i guess this makes sense.

Marv · 10-19-2011, 03:18 PM

I agree. The 1 3/4" has a sharp snapping sound and the 2" has a base sound. Marv

OLD...BILL · 10-19-2011, 05:13 PM

Run the Brockman's Mellow Tone, 2" strait through, and US made sounds great with your size engine.... OLD...BILL

39portlander · 10-19-2011, 05:23 PM

I should not have read this thread. On my 39P/U, 59AB after my Red's was going to run Brockman's (Vic P.) approved, but now I need to hear some more flatties with/without mufflers to see what I want

Steel 35 · 10-19-2011, 10:00 PM

I am afraid to say what size mine is

and there is only one of them! but the thought of a early morning drive by of the earlier morning 4 bangers house is sounding very appealing, next spring it is........Dual Stainless 1.5" would be a very large upgrade.
