Smithy's Glass pack Mufflers

[My 34 Ford]

MY stock 34 with a stock 221 stud engine is going to need a muffler replacement soon. Thinking about changing to a single Smithy's glass pack but need some advice about which length to get. I would like something with a little more authorative sound but not something that is too loud. Is a Smithy's muffler the best choice? What do you recommend for this car with single exhaust. Also if someday I go to a dual exhaust system would this change the length of the mufflers used? Thanks in advance for your opinion.

I like your choice of mufflers, others won't agree. I like Smithy's deep mellow sound. Smithy's has been around since the 50's and some say they are now made in China, I don't really know, yet I run two of them on my `35. They are now 5 years old without an issue. It makes sense the shorter the muffler the louder they are.

The 26" is the middle Choice, that is what I use, not too loud, sounds kinda mean...

I run dual 22'' on my 59AB and it sounds great. Good luck !

I have a single 24" Cherry Bomb Muffler (Straight - fiberglass packed) on my 221 '35 engine. I was disappointed on how quiet it was. It is louder than stock, but not much. I have dual Smitty's on my '34 phaeton and like them very much.

I put 26" Smithys on my '40 coupe and it sounded like an old lady's car!
Made up a pair of pipes to fit in place of the mufflers just to see if it would be too loud with straight pipes.
Six years later it still has straights on it.
Has a nice flathead sound and nobody has complained about noise.

I'm running straight pipes on my 239 also. 1"7/8s out of the manifold to 2" all the way back to the rear of the car. I have the chrome Ford logo tips on the ends. Sounds pretty nice.

I use two 22" Smithy's and they are just right. I dont like 'em too loud, gets annoying on a trip, and I dont like 'em to "rap" on decelleration either.

I got 26" Smithy's on my 55 f100

hey ken, you have no mufflers on your 36 ? are you running duel exhaust ?
just straight pipes from front to back ?

[robert dick]

straight pipes or steel pack Brockmans would be the way i'd go.

In the 1960's my father ran twin pipes without mufflers on his V8 Pilot when he got tired of replacing mufflers. He told me he ran the last few feet at 1 inch diameter. Always got a warrant of fitness (New Zealand) and I remember it as much quieter than the boy racer stuff I hear around today. In the 70's, when I got my F1, I sleeved pipes right through my twin glasspacks (Cooper) when I couldn't get the sound I wanted (to my 17 year-old ear). When I connected the same exhaust up to a 272 a year later it was apparently a bit on the loud side and I found myself doing a 'please explain' to a magistrate (explanation accepted). Today I'm back to the flathead and twin glasspacks (still Cooper but unsleeved) which have a bit of a bark (to my 17+ year-old ear) - I'll try the Smithy's next.

Straights.Listen to something that's got 'em. Flathead of course.

[Jack 34pu]

I have dual Smithy's on 'Lil Red and they are pretty quiet. Had a 53 Merc as a teen with large, long round mufflers (stock?) - it sounded great.

Brockman Mellowtone Steel Packs if you're running mufflers.

Yep straight pipes all the way back [duals]. Nice sound too,not loud at all.ken ct. Keeping the tail pipes small [stock size] makes all the diff in the world.Bigger is louder.

I don't have a flathead but a Yblock in the '56. They come in several different lengths for selective fit and sound.

I run dual Porter steelpacks on it. Nice and mellow at idle but they will bark if you want 'em to. They sound great at cruising speed. I've also heard good about the Brockman steelpacks.

Porters are USA made and if you're a HAMB member he offers a pretty good discount to Alliance members.

I haven't checked lately but there used to be a video of a '48 flathead running dual Porters on their website if you want to check it out:

My Smitty's have been on the 39 convertible over 30 years and sound like concert music. G.M.
