Downpipe question

[Babe the blue OX]

Does anybody out there have their downpipe go straighht out? No exhaust, strsight pipe, cat or muffler.

Just straight out under the cab?

Just curious about this practice. It sounds beautiful but loud.

well there are a few issue that pop up with this and it all depends on the owner..

1. cab noise is unreal under load.
2. everything from the dp back will be covered in dust.
3.its not legal and pretty easy to notice.
4.the turbo will be the onlything holding the pipe up and tends to get loose.
5. heats trans up while stopped.

never thought about it with my red truck but my c10 i have "exhaust cutouts" at the headers for when i hit the strip might be a great alternative.

with that said i think im gonna do that where i cut my cat outnow... wow thanks

Im ordering this now ill post a thread when i get it.


oh i might add it says for electric cutouts.... i just welded bolts to it and have wingnuts holding a plate on not takes 5 minutes to take off but cheper and less prone to failure.

Thanks for the reply. Could you tell me more about the hot tranny issue? Thanks

prolly from the heat comming out of the down pipe. i have a stock down pipe (planning on getting rid of that and going with a 3") and a straight pipe from there all the way out to the back and thats a smidge on the loud side in the cab, have you thought about doing that.

The dowmpipe would be blowing all the hot exhaust right next to/on the tranny.

I took my truck for a spin like that when I was installing the downpipe. It was loud as heck, and the tranny was hot to the touch.
