Is there any performace to be gained by going to a 1 inch header and pipe in a mono ?
I am going to try and run my gas SD3 this season:lol:
Thanks for any input.

Theoretically the 7/8" diameter has plenty of surface area to flow the gases exiting the exhaust port. But I think it is more involved than that, as can be seen with the 2-stage pipes... in my opinion on a single stage pipe, the 1-inch header is better than the 7/8" because it is a compromise between a 2-stage pipe and a single stage with smaller header...if that makes any sense. I would like to see a combination of both now that would be interesting!

All your going to need is just a little patience and a combination of both will appear very shortly.

Sooooo..... what are you saying? Stick with my old header or invest in a new one:unsure:

If you change the header you have to change the entire pipe to match. Or were you planning on fitting them? Let me put it this way, if you are running a typical aluminum pipe on 7/8" header and decide to change it for a Powermaster alum pipe on 1" header...yes you will definitely see a difference.
