: Straight pipe exhaust question.... GMC2500HD 10-13-2004, 11:09 AM Have any of you running a straight pipe had an emission issues? Truck needs to go in for testing and I just wanted to make sure. I am not sure what to think because my truck did not have a cat and now has no muffler obviously... Just curious... ThanksEdited by: GMC2500HD hoot 10-13-2004, 05:24 PM My state of PA doesn't check diesels for emissions but to answer your question, the muffler is a sound control device, not an emissions control device. I have not heard of checks or failures on diesel trucks without mufflers, ever. It may be an issue but I have never heard of it. Edited by: hoot Big Angry 10-13-2004, 08:20 PM Yeah, I straigh piped my 04 (which had cats- but no longer) and gutted my Banks muffler on my pipe (should have made my own from the get go-live and learn). I am exempt from emissions like Hoot because I hail from PA as well, and as long as you didn't have a cat to begin with, I don't see how you couldn't pass now. Good luck!

You pay a little more for your registration but thats just what I have been told.
