wife says it's too loud ! ::)

On one of the warmer days we went for a longer cruise. With the windows down, load on the engine and between 35-50 MPH the exhaust is real raspy and drones a lot. (to be honest it does sound like a race car)  I never really noticed it at first until we were in some traffic and had to follow the speed of traffic up a hill.   

so i started looking for a way to tone down the exhaust. the best option i found was to build spiral or auger style inserts that go into the existing exhaust tube.
these are easy to make and can be tuned to your liking. I made a 6 flute 2.5" version.  (I can always cut them down if i want more sound)
Best part they are removable with a couple of capture screws.

Wow, what a difference they make.   I went for a drive through south bristol hills to put a load on the engine.  Very melllow now, but still has the V8 sound.
Should make longer drives a lot more tolerable.

Do they rattle inside the pipe?

Great solution though!

they are anchored with 1/4-20 screws.

I decided i missed the rumble of the aggressive exhaust.

I installed a pair of electric cutouts that bypass the second auger mufflers i just installed.

This gives the the best of both worlds with the flip of a switch.

I have been rolling out to a bunch of pop up cruise nights and car shows.  Apache gets a lot of attention.   I have not seen one other vehicle on air ride, so i guess the amount of questions I get is to be expected.   https://www.youtube.com/watch?v=d8hddO7g8lU

The auger thing you made goes after the muffler?  im going to try and do something on the two trucks i have- they both have the same problem.  fappy rattle under load thats really annoying.  sound great at idle / idle rev. 

biggest problem ill have, is not much of the exhaust is straight pipe, so i might just cut into the pipe and slip in baffles
