would be a little ... smokey.

haha.

It sounds cool without the DP.
Really quiet.

You'd probably die of CO2 inhilation though.
Our trucks exhaust might smell great, but some oxygen would be good tooo.

Don't think the heat from the exhaust would catch anything on fire?

I'd think you'd maybe get a little oily in there too.

Heater box would probably melt.
Carpet might catch on fire.

Start and move across the shop, maybe.
Drive it down the road, I would not.

400 to 1000 degree exhaust blowing on the floor board, not a good idea if you like your truck.

I have ran mine plenty but I put a 90° elbow on the turbo to make it blow up away from the airbox. Actually a 90° on the turbo and a 45° on that and it will blow it straight up vertically. This is how I made my hood stack. As long as the pipes are not near or touching anything that will melt you are fine.

These trucks sound great like that. Just a tad illegal though. I drove mine for over a week one time like that with no hood.

It gets some strange looks.

I drove by a cop one time and if you let out of it and barely use the throttle you can sneak by them without them even noticing at all.

There was a user down in the IDI section that ran a hood stack, all the time.
Can't remember where he was, but that would get your truck impounded here.

Exhaust must exit behind the last opening into the passenger compartment is about rule #1 in the exhaust section of the vehicle safety inspection book.

Back when (Lake pipes) side pipes were all the rage, the only stock production car that could run them legally in WV was a hardtop Corvette.

You converted your down pipe to an up pipe, that's a little different than just running without anything at all!

I didn't convert it, I made an uppipe and removed the top section of my downpipe. I can now do the swap in about 15 minutes.
