I have a dynomax ultraflow welded exhaust on my 03 2500, just wondering if it made a difference which direction I have it

 

I don't know that it matters but im no exhaust expert...maybe silly stuff like noise/smell/smoke at a drive thru teller (bank) or restaurant. In that case, I'm glad I have my exhaust on the passenger side. Sometimes though, I wish it were on the driver side to smoke out some smart a$$ :-)

 

Don't know what you mean by which direction. Could you elaborate more?

 

I meant which side you connect the incoming exhaust and which side you connect the tailpipe. Sorry for the confusion but thanks for that anyway

 

Mufflers are marked for inlet and outlet

 

Usually have an arrow in the middle pointing to the outlet.

Unless it's a turbo, then it's a flip-fit.

 

I've searched all over and can't find any markings. No arrow, no nothing. It maybe painted over since the mufflers painted black. One port is centered, the other is to the side if that helps

 

If you know the model number, you can check their site.

But if this is already welded to your truck, why ask unless you are having issues?

 

Ok thanks. It's not welded on there yet though, it's an ultra flow welded muffler. Once again sorry for the screwed up wording. But just wanted to make sure I had it right before I did weld it on there

 

Direction is for sound and flow. The internal baffles are directed a certain way to promote better flow and scavenging.
Most arrows on muffler bodies are stamped into the steel and raised, so painting over the muffler, you would still see it. No arrow, no direction.
The Dynomax ultraflow is basically a straight pipe that is in a larger muffler body to assist with a mellower tone. Doesnt matter which way you install it. ;-)
Have fun!
