    what are you guys running for mufflers these days? im building a model a with a blown big block chevy. with all the laws becoming tougher i dont want any problems for being to loud when it comes to inspection time. personally i dont mind any kind of noise but dont want to be hassled either. i was looking at flowmaster mufflers but was told they are loud?. maybe thrush muffler? or how bout tricks to quit it down at sticker time? thanks for any input

    Flowmaster 40 series.

    If Harley's can't be too loud............then why should we worry?

  3. Thrush Turbos, nice and mellow sounding, at least behind a mild 350 SBC. I made my entire system out of 2 inch stainless tubing, it has a nice sound to it.

    I've never used them personally but those flow master hushpower II's are supposed to be extremely quiet and still offer good flow. You could put those on the car and cutouts for when you want to be as loud and annoying as a Harley...

  5. I have Edelbrock SS mufflers on my '57. They sound great, not too loud and will never rot.

    Flowmaster 40's as well. Best part is they were free! Not very quiet though....

    Smithys or Porters. Flowmasters have too much of a a 'musclecar' sound to me. I had a pair of 'Cherry Bomb' turbos on my last project (472 powered 55 Cadillac) and they blew out even though they were nearly new.

    Personally I find Flowmasters too raspy. Magnaflows have a smoother but intense sound to them.

    I just put two of the Thrush generic flowmasters on a Y block. $33 ea out of summit and I think they sound great.

    I have some of the old Flowmaster "Big Block" mufflers on my 55, with full tail pipes, they're pretty quiet from inside the car. They're heavy and really big. I have 3" pipes front to back.

    I've been thinking about putting something else on, but I don't know what.

    I've got a Porter on the Buick, soon to be dual Porters. The single sounds really, really good. It sounds deep and sinister without being deafening.

    Porters will be going on the '62 Longroof too, once we get past rust-abatement...

    Red's headers into Smithy's with my 8BA, sounds just right.

    I run stainless magnaflow turbo's on the Shoebox. Sounds good, not too loud. I run Thrush welded on my dailey driver with an LT1 and it sounds great w/out being annoying.

    Um, Its a blown BB chevy, not a flathead:rolleyes:Porters or smittys would probably cost in the area of 75-100hp on that motor...Magnaflows or 3 1/2" Dynomax ultraflows. The longer ones are quieter.

    Sorry but to me a blown big block and Porter mufflers do no go together. My 34 P/U has no mufflers, zero, nada.

    I love both styles but do not like it when they cross contaminate. I'm using Flow master clones on my 56 project just to get that thumper sound. 2 completely different style cars with completely different exhaust systems and sounds...I love them both.

    A 50's style hotrod should not sound like a thumper car and a blown BB should not sound like a 50s hotrod. JMHO

    Wondering if anyone has experience with the Magnaflow Turbo design mufflers, same size as a regular Magnaflow that are really a straight throug design. The ones I am looking at are 4 x 9 x 14 cases.

    Going thru the same quandry here for my Model A with a 425 Buick running 2.5" pipes. Not a lot of room under a A.

    One or the regulations here (not necessarily enforced but a regulation that could be used against you) is No Straight Through Mufflers :mad:.

    Thanks for the heads up on the Cherry Bomb turbos blowing out, they were one of the mufflers on my short list. Liked the small size but wondered about the single layer case.

    Looks like I am looking for the same thing as Cayager.

    Thanks from both of us for any help.

    Smithys, swapping to Porters as I plan on redoing my whole exhaust. Having a good buddy that owns a muffler shop that is annoyed with the quality of work on my current exhaust system helps:D

    Don't forget about the Brockman Mellow Tones. That's what I have, though they are not installed yet so I can't provide a sound clip.

    I have enjoyed the low rumble of SS Magnaflows behind Dynatech headers for four years now. They do not resonate like 2-chamber Flowmasters. I fought the local muffler shop who gets most of the muscle car business in the area. He is a Flowmaster dealer and really tried to push the flowmasters on me. I was adament and said no way. He also got a little annoyed when I told him I wanted the tailpipes tips to be within the "angle of departure," and exit like a '69 Camaro's.

    Some you have heard the sound of my car. It's a big block 6 with a 270 cam, 2 1/2" pipes through a pair of "18" chambered" mufflers. The 40 sounds like a bad V-8 when idling, but like a one half a P-51 Mustang when you get on it. I've seen grown men clasp their ears and teenagers cry!
    It's a beautiful thing!

    I have Summit brand turbo mufflers on mine, and they're mellow.

    thanks for the replies. im not so worried about the law around here, ive rarely heard of guys getting pulled over, once in a while but not very often. i dont want to open a can of worms at inspecton time. i will check out all of your suggestion. my buddy have the flowmaster 40's he said they were really loud. you hate to build a whole system around one thing and have to cut it apart to fit in another. loud engines are music to me but not to the state i guess
