    Clarence will be partially disassembled this year. While this is happening the ram horn manifolds will be replaced with block hugger headers. I'll reuse most of the exhaust piping, which is 2 1/2". I want to replace the mufflers while I'm at it. The no-name mufflers that are on it now were supposed to be deep and throaty sounding. Not so. The exhaust sound is just fine at idle, but up the revs any at all and it sounds tinny or shrill. What mufflers do you guys/gals like (that you are using or are actually familiar with) that sounds good up through the rpm ranges?

    I've had glass packs on it before that sounded ok but they burned out quickly and then sounded like crap.

    If the consensus it glass packs what brand will last a long time and keep the good sound?

    I've run straight pipes on my avatar for 21 years, my 59 Ford for 17 years, and my 39 Ford for 17 years. Nothing makes music like straight pipes on a Y Block
    My Y Block had a sharp sound that I didnt want so I made some 'can opener' type baffles and put them in the ends of the pipes for a softer sound

    I have used Flowtech Afterburners with a crossover that sounded good to me.

    I like the 40 series Flowmasters, nice sound without being too loud!

    What exhaust company was it that used baffle plates? I didn't use them but I think that the sound
    and exhaust flow changed with the adding and removing of the baffles.

    You could always install some resonators to reduce shrillness. I've always liked 2 1/2" turbo mufflers, turbo's are a bit less obnoxious vs glass packs (or steel packs), but flow very well, so they don't cost a lot of power. I have a set of turbo mufflers on my 47 coupe w/ sbc, and they are nice and mellow, until you put your foot in it. Walker is a good brand. For glass packs Porter is a good brand, as are Smithys . I'd avoid the Cherry Bomb and other cheap brands, unless you really want to annoy the neighbors.

    The original turbo muffler, Walker #21348 (# now extinct)was 2 1/2" in & out. It was the (turbo)Corvair replacement muffler, & the muffler that started all the hubbub about turbo mufflers. I've used several sets over the years, still have one original set on an OT. I believe Walker still offers it in their DynoMax line under a different #. Deep, smooth tone until you romp on it. None of that glass-pack rappity-rap. Highly recommended. :D

    My 56 Belair 2 door post car has a warmed over 327 with fender well headers, an "H" pipe, Flowmaster 40's with tail pipes out the back and the best exhaust sound I know of. The 63 Impala in my avatar has block hugger headers with Flowmaster 40's and exits in the stock location just behind the rear wheels and sounds great as well. I believe an "H" pipe makes big difference.
    The problem with mufflers is you never know how they will sound until you install them.

  12. I had Summit Brand glass packs on the Pusher. 28" long as I recall. I ran them for 80K and I think it sounded OK. Would have sounded better if I ran full length exhaust instead of the sneaker pipes.

    Anyway you heard the Pusher you can decide from that I suppose.

    I use Powerstick mufflers on my '50 Ford with a warm 302. Not too loud at idle or cruising but they make some noise on accel...

  16. I'd say long Brockman steelpacked mufflers. Won't burn out and will sound killer.

    X2 on the Brockman steelpacks. They sound really good on my flathead, without being obnoxious.
  18. Brockman Mellowtones yet again. Steelpacks not glass, he does both in various lengths and diameter.
    Many many years many many miles.

    If you want a traditional sounding car, forget about the Flowmaster and other chambered type mufflers, they may flow well, but they do NOT have a traditional hot rod sound. Especially when you add an H or X pipe. That is an 80's exhaust sound. IMO there is a aural dissonance when you see a traditional looking car or hot rod, and it has an 80's exhaust tone.

    Smithy's, 2 1/4" pipes, no cross over, reds headers, flathead.

  21. I am a fan of the really deep rumble tone like hrm2k's aboveHowever the sound the majority of hot rods and factory muscle cars nowadays is a high flat, tinny sound. Sounds to me like a Rice Burner wearing a fur muff. Don't know whose product they use but not a good sound.

  25. I think part of that is do to the 'X" or crossover pipes. Not as distinctive as one without the x.
