Straight Pipe Vs Thrush Glass Pack! Slant Six Exhaust Muffler 1972 Dodge Coronet Obsolete Automotive

This '72 Dodge Coronet had no muffler when I purchased it. It was pretty loud, so I decided to go with the cheapest muffler option which was a Thrush Brand glass pack.
In this video I show I go over the muffler and then you can hear what the car sounds like without any muffler and with the new glass pack.
It's a short video but good comparison.
There is more work to do on the car... but at least it's not obnoxiously loud now!

I love this car. Something about low optioned vehicles just does it for me.

[@johnkendrick7304]

Sounds a hundred times better with the glass pack and very nice that you got rid of that stupid thing hanging off the back

[@calvincrews3885]

That Dodge Coronet four door sounds great any muffler can be available at the most you won’t get in trouble with the law and other neighbors

[@georgewilkinson1068]

I was pleasantly surprised. I'll take the glass pack over straight pipes any day.

[@ObsoleteAutomotive]

Way better for sure!

[@jonshellsr.7900]

Much nicer sound! That is very considerate of you to think of your neighbors. I wish more folks were like that.

[@ObsoleteAutomotive]

The no exhaust was pretty annoying to me… so I can imagine others would think even less of it! Now it’s much more acceptable!

[@krusher6969]

Nice car. My first car was a '72 Coronet. I've since had two more. All with 318s. If I get the chance, I'll buy more of them.

[@daviddisandro821]

i love that car. i d use that as a daily driver. real cool

[@ReaperRestorations]

I put two of those on my 318 swapped '46 Dodge deluxe....it was much louder than I expected. but it does sound mean!

[@Madinfidelprepper]

I remember using one in high school on a V8 maverick lol. It kept blowing off from back pressure. Crazy but I miss that damn car now.

[@JoeBritton-mw5yk]

Sounds much better with the thrush muffler for sure. The only drawback is you might have a drop in your fuel mileage......but hey, get that carb adjusted correctly and you'll get it all back and then some. Love your video's, keep them coming Austin.

[@ObsoleteAutomotive]

The carb definitely needs some help. It’s on the to do list!

[@TylersNeighborhoodGarage]

Good old Holley 1920...2 parts fuel to 1 part air.

[@ronroberts2453]

Sounds much better, great idea Tex!

[@johngidman4574]

That thing is running rich 😮

[@lsswappedcessna]

That took a surprising amount of rasp out of it!

[@beljames1563]

My opinion is that the six's from that era don't sound great at best. So the quieter the better. Its unusual for that late of a b to have a six. So cool car.

[@vincemajestyk9497]

Don't expect it to last too long. I did the same thing after I had a bad carb that blew up a couple mufflers. Those modern day glass packs are cheap as $hit. My glasspack was a hollowed out core in less than a year. The best 'cheap' muffler to get is the Walker Sound FX. I've had mine on 5 or so years now and it has an OE style Mopar 'Hemi' muffler rumble. Number 18230. Cheap. Nearly the same as the glasspack but quieter and lasts longer.

[@tomtbi]

Sounds quite a bit better!!

[@davidcorliss]

Sounds much better

[@jeffreyrigged]

I really like that car. I wish i had bought the 440 police package car that color i talked about in another video you had on it.

[@darrellmoore1743]

Nice car!

[@dh2360]

I am also looking to be an owner of a 1971or 1972 Dodge Coronet and Plymouth Satellite sedans, preferably with the 318 engine. They will make for some very cool drivers.

[@ObsoleteAutomotive]

They are nice drivers.

[@martayking8694]

I had Thrush deep tone mufflers on my 67 GTO back in the day, and Cherry Bomb muffler on other car back then.

[@steves9905]

luv this car. I'd be tempted to take out the PS just to complete the image

[@racer6583]

The only time that a muffler is not wanted is when you drag race track only car. On the street a good flow exhaust is needed to get decent fuel mileage and a nice sounding exhaust doesn't drone your ears to the brink of insanity.

[@danam0228]

I kind of liie the sound of the straight pipe more, but imagine that in person is too loud, especially when driving for more than 15 or 20 minutes. Getting dirty looks from neighbors is never good either

[@waggitnshaggit6592]

The Salamis (glasspacks)are my go to mufflers and they last forever

[@ObsoleteAutomotive]

The salamis… im gonna have to use that term.

[@jamesashabranner2426]

Yeah it was quiet it down a little bit 😁

[@frankfurther3828]

sounds good, The glass pack may not last long and it will be loudish again

[@codyscollay8569]

Sounds pretty good, anything done to the motor, idle is pretty stout sounds least on video

[@ObsoleteAutomotive]

I think it’s all stock and original.

[@buckster2575]

I like it alright.im not hating.shed man had a 68/69 Plymouth fury lll it had a slant six and three on the tree.

[@glenbo2464]

Yah , that carb is loading up. Easy fix though ! Sounds good.

[@ObsoleteAutomotive]

Yea fixing that carb is on the many to do lists I got around here. Ha

[@Scouten819]

both sound good but i think the straight pipe was alot nicer.

[@jrnelson2106]

I just bought a 73 coronet with a 318 and I just bought the same glass pack

[@ObsoleteAutomotive]

Sound pretty good?

[@fordssuck]

A Flow monster, not Flowmaster, muffler would've cost about the same and sounded better

[@fordssuck]

I'm looking for a nice vintage Mopar, where are you finding all these cool cars?

[@ObsoleteAutomotive]

All over the country. I got several coming up for sale.

[@jamesashabranner2426]

Yeah most of the cars I find are rusted rotted out humidity got most of them and salt on the roads I'll still look to the woods trying to find them hooked on Facebook market they're asking big dollars for rusted mopars 😁

[@joemazzola7387]

You could have to pick a part with a tape measure and a sawzall Modern mufflers are stainless steel

[@michaeladamo1188]

That is a awesome car! Is it by any chance for sale?

[@ObsoleteAutomotive]

Yes it will be but I haven’t listed it yet.

[@michaeladamo6279]

Ok lmk when you’re ready. Ware are you located?

[@ObsoleteAutomotive]

@@michaeladamo6279 North Carolina. You can email me ([e-mail]) or message me through Instagram (@obsoleteautomotive)

[@wazzup948]

Do you sell these Mopars, or a collector with a problem?

[@ObsoleteAutomotive]

More of a collector with a problem but I do sell some here and there.

[@louislepage5111]

With all the vehicles you have and not one set of glass pack mufflers?????😊

[@ObsoleteAutomotive]

Not any that I’ve put on! I have one car with rotted out glass packs and another with new ones but I didn’t add them. 😂

[@louislepage5111]

@@ObsoleteAutomotive ok fair enough, enjoy the Coronet 😊

[@wodanowitz]

Good Video ... the Glass Pack sounds great 😊

[@PecanRanch]

Duals on a slant six with glass packs sounds great, I had the setup on a 225🎉
