In my circle of off-road buds we all call it a dumped exhaust. Anyway, is there any benefit to it? I had my CJ I-6 dumped with no catalytic and a flowmo and everyone thought I installed a 350. A good sounding truck is bad ass, but is that the only difference???

It spreads out the sound around the vehicle for 1. Another thing is that you can cut it so it wont hit on anything while off-road

I had a turndown for about 2 days and then I cut it off and just ran it dumped out of the muffler...sounded like shit with the turndown.

I think another benefit of a turndown is that when going through water, there is less of a chance of water getting into the exhaust (muffler). With that being said, I have cut my turndown off and now run it dumped right after the muffler. My air tank wouldn't fit without doing so.

Yes, and yes... I did it on mine for the clearance issue...

On diesels guys do it so the soot dissipates before it coats your trailer, and coat it will....

typically clearence is the main thing - if you are consistenly in the upper RPM range on a high end application (i.e. drag appliction running high RPM) the dump right off the muffler is best for getting rid of exhaust gases that much quicker

What does it do to backpressure, negative/postive? Just curious, I have mine chopped over the rear axle already.
