Guys i have a ? for you all what kinda of mufflers are you running Im running fender well headers on my 55 and need a exhaust system to run it on the street. How do SMITHYS compair to FLOWMASTER or CHERRYBOMBS?
Years ago, Hot Rod or Popular Hot Rodding did a muffler shoot out. Flowmasters gave the most power, but were also the loudest. Don't know what the current standard is, but I've run Flowmasters ever since.
From my own experience, Smithys have a mellow, low tone to them to where gl*** pack's, or cherry bombs have a much more sharp sound and more 'rap' to them. Flowmaster's pretty much have the modern muscle sound. The sound will have a lot to do with the motor the're attached to as well.. If you have some heat under the hood then it'll change the exhaust note. I have fenderwell header's on my 57 chevy as well, and i tied it to 2.5" exhaust with flowmaster 40 series mufflers. I wasn't so much concerned with era correct, just liked the way it sounded with them on. I had both gl*** packs and Smithys on it at one point...the packs sounded like **** with that motor, wayyy to much crackle for me and the smithys were too quiet. Personal preference. Tony
I've been wondering the same thing. I'm running a 235 inline 6, and will be picking up Fenton headers soon. Should I run straight pipes, Smithy's or Cherrybombs?
Apples and Oranges, man! What do you want, performance, or great sound? Fifties sound, or modern sound? Make up your mind, then go shopping. My suggestions, Brockman Mellowtones for a great 50's sound, lots of cackle and rap. 60's hot street machine sound, maybe Thrush, Cherry Bombs, or quieter turbo mufflers. If you have a Mustang, GN or Camaro, Flowmasters.
I have Flowmaster "Hushpower" mufflers on my Buick with a SBC 355 with Trickflow heads and a 270 Comp cam, it is very loud and raps like hell.
Brockman's, Cherry Bombs or generic gl***packs will all give you that nice, mellow tone with lots of rapping when you want it. They sound good on almost everything. The longer the muffler the mellower the tone. Flowmasters sound like you have a garbage can for a muffler. These might be the "in" thing right now but they sound tinny and cheap... IMHO.
Don't Smithys come in a max inlet/outlet diameter of 2"? A bit limiting if you're running a 2 1/2" exhaust system. I've had several muffs on my 32 roadster with 462" Buick engine. The present day two chamber FlowMasters are ok, but a touch loud for me. I had a pair of gl***-packed Turbo Muffs from Summit - made by Walker - and they had a nice sound. It can be tough getting muffs under the 32 cuz there's not much room. If I had the room I'd be running three chamber FlowMasters or maybe a pair of Hemi-muffs. I have a pair of three chamber FMs on a true dual system on my 2002 F-150 with 5.4L engine and they sound a lot like a steel or gl***-pack from the good ol daze. Running open headers or no muff behind a stock engine on the street makes the car sound broken. It's all about the music and not the noise. I don't think some wanna-bee hot rodders would know internal combustion music if it reached out and bit em on the ***....
What are you looking for, max power or a certain sound? Older style gl***packs don't flow like the modern aero chamber mufflers and if you have a big mean honker of a powerplant might cost power. But then there's that whole thing about sound.........
