Beemon Posted January 15, 2018 Share Posted January 15, 2018 I've been searching for this information and so far have not turned anything up. This has been one of my biggest regrets on my car, mostly because it was in the hands of my father and he "convinced me" with his money to go straight pipe front to back with Magnaflow mufflers (originally wanted Flowmaster). When I got my old pipes back, they had simply just cut them up because they were perceived as junk. I had also tossed my original mufflers because they were perforated and collapsed, not donning on me that I could have taken them apart and possibly reconditioned them. The loud exhaust appeal has quickly worn off and it's really annoying to try and have conversations in the car. My grandfather also detests them. I'm thinking about just getting a Walker muffler or OEM equivalent and be done with it, but would like original length of the mufflers so I can pick accordingly. I want to say I recall them being about 36" or so. Really just want the Buick to be quiet as it should be and stop mucking about with obnoxious mufflers. I want to be that humble guy that rolls up and parks in the back of the show unnoticed that you spot out of your eye versus the guy everyone judges silently and gets all the attention. Since my exhaust system is already butchered, I'm just going to cut the pipes and clamp the new ones on. Thanks in advance guys. Grandpa isn't doing very well these days so I just want him to enjoy it the way he remembers, quiet and strong. I'm also getting it painted this year, so it should be a fun year. 7 Link to comment Share on other sites More sharing options...

Beemon Posted January 15, 2018 Author Share Posted January 15, 2018 Is it quiet like an OEM muffler? Link to comment Share on other sites More sharing options...
Beemon Posted January 15, 2018 Author Share Posted January 15, 2018 So I stumbled upon this today after looking at "Walker Exhaust Classic Cars" on YouTube. 1961-64 Chevrolet used 2" pipe on their exhaust and the 327 is close enough to a 322, they should be similar, right? They look about the same size, at 27" case end to case end, and this is their stainless steel model (I've heard the aluminized mufflers don't last much longer than a year or two?). Might just be what I'm looking for. Still hoping someone will chime in with the OEM muffler length! Link to comment Share on other sites More sharing options...
old-tank Posted January 15, 2018 Share Posted January 15, 2018 The 55 muffler case is about 30" long and 56 may be similar, but the clamping was different: 55 used slip fit, the the 56 introduced a ball/socket arrangement commonly called back the day "Buick Clamp". From Waldron site: On one car that I restored, I removed a 20" muffler that was functioning and fit ok, but not for a restored car. It seems that yours is already far from stock, so have a muffler shop install a slip fit with the needed inlet/outlet size and offset.

avgwarhawk Posted January 15, 2018 Share Posted January 15, 2018 I have a standard Walker muffler on my 54. The car runs quiet. If your current pipe is far from stock as Willie stated, the Walker universal fit muffler will quiet the engine as you desire. 1 Link to comment Share on other sites More sharing options...
g-g-g0 Posted January 15, 2018 Share Posted January 15, 2018 If you are still needing the length, give Waldron ‘s a call. They do not manufacture their replacement mufflers but have a source that supplies OEM type mufflers. I suspect they can help you. 1 Link to comment Share on other sites More sharing options...

Beemon Posted January 15, 2018 Author Share Posted January 15, 2018 (edited) Al, thanks for the offer. unfortunately I would have to buy a whole new system to fit that one muffler, and would still need to find a second one. I can say now though that that muffler is different from the ones I threw away because the exhaust hangar was on the ball socket clamp on the inlet side. Thanks for the replies everyone. I'm glad to hear about the Walker mufflers, I've just heard they rot quick. Willie, I wrote down that gentleman's information. Hopefully maybe next year or so I can replace the entire system to go back to OEM, but not this year. Edit: ill be driving to Michigan in May for the formula SAE competition, wouldn't it be convenient to have it replaced while playing with 600cc go karts.

As much as you drive your Buick the mufflers would have no time to rot out! Let us know what you do with the system. 1 Link to comment Share on other sites More sharing options...

If your current pipe is far from stock as Willie stated, the Walker universal fit muffler will quiet the engine as you desire. Do you by chance know what muffler you have on there? I had a lengthy phone call with the girlfriend today. The first 30 minutes was me explaining to her what a muffler is and where to find it. After getting pictures of the transmission oil pan (told her it's a box with pipes coming out of it ???) I told her to go the other way. Being 5 hours away from the car, I want to make sure I get the right mufflers. Installed I have the 3x7 (guessing, doesn't matter) Magnaflow 14" with offset inlet and center outlet. I also know I have 2" pipes front to rear. I've heard using the longer Magnaflows are better for sound but why bother? So it looks like I'm limited to the 4x8 Walkers with an 18" case. I guess I could go to the 26" case ones, but they're 2.25" inlet/outlet and I don't want to use a bunch of adapters. I've heard good reviews about the Walker sound, but most cars running them have resonators. The mufflers for the 55 to 64 Chevy also have the wrong inlet/outlet positions and therefore cannot be used. I'm pretty sure they flow one direction, but I guess a phone call can't hurt. Anyways that's where I am currently on this. I don't have a big enough pipe cutter so I'll be using a hack saw... haha Link to comment Share on other sites More sharing options...
avgwarhawk Posted January 17, 2018 Share Posted January 17, 2018 I do not know the Walker muffler number. Installed already when car was purchased.

avgwarhawk Posted January 18, 2018 Share Posted January 18, 2018 (edited) Beemon, Muffler measure 18x11. The engine was rebuild in 2006 by the previous owner. I suspect the exhaust was on before that or installed with the new rebuild. Of the receipts provided his wife, none had mention of exhaust. Quite possibly older system than 2006. I got a few pictures. One with numbers that may work for identifying it with Walker. Rear center outlet: Off set towards the driver side: Numbers found. Appears to correspond with Walker Universal Tru-Fit Mufflers 18177 How it looks hanging. Some is tucked into the frame.

That is always the case, but he will send the tail pipe in 2 pieces to avoid the oversize charge. And in the case of my 55 he supplied the "bend card" to have it fabricated locally! This image will not help you and if you find a card for yours you would need to find someone who can read the card and produce the correct ends. 2 Link to comment Share on other sites More sharing options...

I'm also jobless currently going to school so I have to account for livelihood. I understand completely. I can truly say that! In my college days(1986) I was driving a 73 Buick Estate wagon. Come to think of it, I installed a Riviera dual exhaust system from Walker on that Estate wagon. Funny part about it, I was hoping for some growl at the tailpipes. It was quiet.....thanks to the Walker mufflers. DOH! 9 passenger Porsche she was. Good luck in school! Link to comment Share on other sites More sharing options...
Bloo Posted January 19, 2018 Share Posted January 19, 2018 Consider drilling a tiny hole at the lowest point in the muffler to let the water drain out. Not too big or you will hear it talking. Did you say 2 mufflers? Dual exhaust cars are especially prone to dropping the bottom out of one or both mufflers. They fill the muffler up with water from the combustion process, and it just sits there rusting its way to freedom. The mufflers never get hot enough to boil the water out. The further back on the car they are, the worse they rust. The bottom will drop out of the muffler on the heat riser side in about 6 months. On a car without a heat riser it takes a bit longer, but the bottom falls out of both of them. All of this assumes you are daily driving the car. I suspect this is the real reason most cars were built with single exhaust during the time when dual exhaust was fashionable. The automakers didn't want to warranty a bunch of mufflers. Drilling a hole is no panacea, but it helps. Glasspacks cure the quick rust-out issue, but are the wrong answer since you want quiet. 1 Link to comment Share on other sites More sharing options...

KAD36 Posted January 21, 2018 Share Posted January 21, 2018 Slip fit - expanded about 6 inches just before the peak going over the axle. Worked out good on my car because I had added a hanger up there to help hold the other fit not so good exhaust in place and reduced the tendency for it to twist. You could certainly weld it if it suits you. 1 Link to comment Share on other sites More sharing options...

Clamp will work. It is a fitting of two pipes together like other parts of the exhaust that require an exhaust clamp. If I get it in this week I'll sho0t over a picture.

Honey do list is extensive and expensive. Ref my shoes to size the muffler. It is large and in charge. This is the over the axle cut for reducing shipping costs. Works ok for me.

avgwarhawk Posted January 25, 2018 Share Posted January 25, 2018 As a side note, the Walker muffler being much smaller than what should be there, the installer welded a pipe in to account for the shorter Walker muffler. 1 Link to comment Share on other sites More sharing options...
Beemon Posted January 25, 2018 Author Share Posted January 25, 2018 My budget right now is a meager $400 right now and the dual exhaust comes out to $350 before shipping. It's starting to look like a next year project for me. Thanks for sharing! I wonder if the mufflers are made 1:1 the originals with no packing and a straight through baffle. One of the things I found out about the original mufflers is that they are heavily chambered and baffled with two tubes, no cross over, and they look like a modern turbo muffler. It was probably a 2 in 1 muffler and resonator, though I guess 57 adopted the Cadillac resonator setup in the tail pipe. As it currently stands, there are a few smaller things on my wish list as well. I think for now instead of replacing the muffler, ill see about installing resonators at the tail pipe to mitigate drone. Most likely if i were to replace the muffler, the drone would most likely still be persistent based on others findings. The resonator might also shave off that extra db. I'm currently in the process of trying to map the resonant frequency conditions of the exhaust system per firing order, ID of the tube, etc. to see what can be done on a budget. Mr. Johnson's prices are more than fair, I just wish my text books this semester weren't $500. Link to comment Share on other sites More sharing options...
