Muffler Change ‘69 Charger 12

[BrianKoch 293]

Gentlemen,

 

I just changed the muffler on my ‘69 Charger 12.
 

There are quite a few Gravely 18543 aftermarket mufflers out there so I decided to purchase 2; 1 from Amazon for $45 and 1 from NAPA (7-03679) for $72. Both are made in Taiwan and while the Amazon muffler actually felt a tad heavier to me, its welded construction was poorer so I decided to use the NAPA muffler.

 

To complete the installation, I needed a 1.25” x 4” black pipe nipple and a 5/16” x 1-1/4” exhaust clamp (NAPA 733-5323).

 

In conclusion, it seems to me the sound out of the Gravely style muffler is noticeably quieter than the classic pepper pot. Worth the $80 to me!

Much better, personally I cant stand the sound of shower heads, I've got about 5 of them in my scrap bin. Nice job.

There's no worse sound than the pepper pot mufflers, its like the air is forced through the holes and it makes this harsh crack like a whip.  Add a 45⁰ elbow to that to push it out front and the sound will be even less harsh.

That's the same muffler I run on the '75 C160 Automatic.  Quieter than a pepper pot and a lower tone too.

I have a similar muffler on my 867. They definitely are a bit quieter.
