New Mufflers

[VOETOM]

Had a few spare parts left over and needed to use them up. So, my pals and I built two of these monster mufflers for a friend of ours. He has an earlier B- body but I modeled these after ones we made for Brian T's A body 67 Dart (from a few years ago).

These have 3" tubes in and out and a 21.5" body that is a 5" by 11" rounded off oval.

The inner core is a 3” spiral wound version used by the best muffler makers to get flow and really nice sound.

The core is surrounded by about 3/8" inch of tightly wrapped stainless steel wool and the rest of the muffler cavity is packed with a ceramic used to provide the best high frequency sound control.

These will flow like UltraFlos and sound more like the best Goerlich Xlerators from a few years back.

They are heavy and have a 409 st st 16 ga shells, 16 ga 304 end caps, and 304 and 409 st st cores and end bushings.

The last image is of the A Body ones we built for Brian T's car.

Awesome Tom.
Same size as my FM big block muffs, but I'd bet they flow a bunch better.

Nice work Tom!

 

[VOETOM]

Thanks.
Brians were not st. st. and that is why I used the awesome copper stove paint on them. That darn paint was high five years ago, I bet it really costs now! I'll share a photo or two after I find them.

 

[VOETOM]

Here you go!

 

[4spdragtop]

Ooh those look awesome!

 

[VOETOM]

The new st. st. long ones should be smooth and quiet with a bit of a low rumble under harder load.

The mufflers that Tom built me for the Dart sounded so good, my buddy was always jealous of them. Now, Tom has built our friend some and his are SS. Can't wait to hear them on his big block Coronet.

When my Dart was stolen a couple of years ago, another friend bought the car at a salvage auction. I made sure to get Tom's mufflers and custom 3" pipes from him. They'll be going on my Duster when my new engine is ready later this Spring.

 

[VOETOM]

Got the other one home. Just for reference, I put an early 1980s (I believe) turbocharged Corvair 2.5" in and out muffler (replacement) next to these to show just how big they are. Can't wait to get them on the car to hear how smooth, quiet, and sort of rumbly they will be .

@VOETOM Tom, are you still planning on another run of VOE mufflers?

 

[VOETOM]

I have two in work but are having trouble with them. That is where some of the parts came from for these. They are going on a 465 cu in Jon Kaase equipped 70 Mercury Cyclone Spoiler. We ruined one pressing it into the shell and have had to reengineer it all to get them together. I'll share images if I can ever get them together correctly.

Dare I ask what would a couple cost and the wait time would be? I will likely be changing my Duster to 3" and will need two mufflers when the new motor goes in.

 

[VOETOM]

If you had to buy parts and pay labor and welding for the two simple ones, above, they'd be at least $250 - $300 each. Welding done is around $125 to $150 each. Fortunately, if you are not worried about getting the length like I was, you can buy 20" Magnaflows and 22" XLERATORS that are very darn similar for $150 each or so. Maybe not st. st. but they'd never wear out anyway

 

[VOETOM]

Sorry, I was way off. These, perfect for big MOPARS with power, are only 70$ at Summit. Not sure where they are made now, but when they were $110 or so, they were made in USA. These are great and this is a steal.

I have those XS2589s on my car and they sound great. They were about 110 bucks when I got mine.

How are they for drone?

 

[grimreaper]

That is one reason I really like them. Drone is almost non-existant with tailpipes all the way to the rear of the car.

 

[VOETOM]

That is what we found on Dad's wagon too. Virtually no drone and a nice smooth sound.

 

[VOETOM]

Darn it. You just can't go from $110 in USA five years ago to $69 with no significant changes in design or manufacturing processes.

That's a shame.....

How are they for drone?

i have these on the dart. 340 manifolds, 2.5" TTI exhaust with X-Pipe. the drone is loud as hell.

You could maybe splice in a glasspack/resonator after the x, before the mufflers. It might help.
The elegant solution for the drone is a helmholtz resonator.
Google helmholtz for exhaust. (There are guys that have done some, either here or B side).

i'll find a better fmuffler that doesn't drone one of these days.. i really don't want to shove in anymore then whats already under the car ..

Probably later this year in gonna be looking for a couple of muffers for a truck project I have going. 360 mag motor, gonna be a worker not a show queen, lots of long highway runs, I hate flow master (at least the 40s/44s). I was thinking about trying some of their 50s or maybe 70 series. They have a line of "truck muffers" I was looking at. I've had magnaflo before which I've liked (at least the version I've had) better than most flow masters I've heard... I can't tell you the numbers though of the magna flows I used.
I definitely want a "muffled" sound over straight pipes, no drone, I don't want it "brand new truck" quiet though. Some of the regular "muffler shop turbos" of 25-30 years ago had a nice sound, I also used to like the sound of new fresh glass packs but I'd always use the longest glass packs I had the room for. The shorter ones sound the same but much louder. Which I don't want . And I know all of them are quieter when new than after they start to get blown out. And inevitably there will be some in town speed up, slow down, speed up, slow down, repeat.... Which is when a loud muffler is the most annoying except for when you're cruising at the "drone speed"
It will be true duals no cats, whether manifolds or some form of headers to be determined yet as I collect parts by what "hits" when I see it ... I already have several sets of stock magnum manifolds and a set of shorty's that need a little bit of work ( the seal ball on one of those is smashed in like something got dropped on them) not sure if they're worth fixing or not.

For something like that I would get two of the long case Dynomax Super Turbo mufflers and put some glass packs in front of them to kill the drone.
