Open downpipe

[dannyf]

so I ordered my exhaust and it will be here in about a week so until then i am running straight downpipe. Is there any cons to this besides deafness.

[Davey~do]

Deafness indeed! Other than a diesel soot undercoating, should not hurt a thing. The turbo creates all the backpressure the engine will need.

I did it for a while, it was a lot faster.

man i ran man like that for...3 months i loved it lol so loud

[Fuxton]

You'll be fine. I did a 2000 mile round trip running an open downpipe. Noise wasnt really even an issue and there wasnt too much of a smell either.

I think I might just give this a try... I'm straight piped now, but it would be interesting if it gets any louder...

I drove mine from PHX to SLC and back one winter with just the downpipe. My ears we ringing for a couple days after the trip.

I know this is a older thread but I have a question about running an open downpipe. I would just like to confirm with the people that have done it that it wont harm the truck any. I'm waiting for the other half of my exhaust to show up and will have to move my truck out of the shop halfway through the job and just want to make sure it wont hurt anything. May drive it alittle. Also if everyone likes it so much why do they end up putting the rest of their exhaust on? Just curious?

basically if you dont, it will soot up the underside of the truck badly. Ask STUMP, his excursion was ran that way for a long time and it RUINED his interior of his Ex. the headliner was so black. You were always dirty when you sat inside his truck. thats reason enough not to do it to me. Stump changed his back to full exhaust, and he wont ever do that again he told me.

other than that, no performance gains or loss by doing it.

our dump truck dumps a little behind the cab, no problems at all. its jsut a matter of preference whether you can stand it or not.
