I'm no scientist but pure CO is 3 percent lighter than air. I misspoke about it being heavier. I can tell you that I installed a CO monitor in my garage and it took it almost 10 minutes to hit 25 ppm (still at OSHA acceptable level) with the doors down. How long would it take it to reach that in the open? Again, before catalytic converters exhaust had 25 percent CO now they have less than 1. On a cold morning you can see where the exhaust flows and it rolls out the back just like it did with the tailpipe on it. Theres no big cloud sitting under the jeep stuck with nowhere to go but into he cab. It works fine on my Jeep. If you don't trust it, don't do it.

 

Any idea if this is the muffler you went with?

Not really wanting a loud muffler, just one that fits in the relocated position...sounds like this one will work good

 

Awww man I was really hoping you would have a sound clip of this set up cause Im really interested in running it. How would you compare it with just the sound of removing the muffler?

 

Here is a sound clip from WOL of this exhaust. Thanks again WOL.

Thanks for the clip! That wouldnt happen to be the Rockcrawler design would it?

I asked about the comparison cause Ive driven with the muffler off and it wasnt that bad.

 

That would be the Rockcrawler design.
And exhaust noise is pretty subjective, with the top off my Jeep all I hear is loud tires and a little bit of music.

 

That looks like the one. That's even the place I bought it.

Awesome!!! I think Im going with this set up next cause I smashed my stock muffler
