It sucksI went from 13.2 to a 12.7 because the air was actually good quality
What was the MPH difference between the 13.2 and 12.7?
Another batch of Billet Manifolds

We sure do Andy! Our stainless 3" downpipe is made to work with true 2" round up-pipes on the factory chargers as well!
So I'm guessing I'm screwed for getting the 2 inch up pipes on my truck with a 3.5 inch downpipe!!
^ would like to know this as well, or about how much firewall "massaging" needs to be done

I was able to build my 3.5" Downpipe and our full 2" up-pipes. A lot depends on which pedestal you are running. It is tight fitting both full tubes through
I've got a turbonetics t4 its 5 1/4" tall. What pedestal and height did you run to make em fit Joe?

Wondering if anybody has installed these on a truck where they're not running HSP's 3" downpipe? Any issues fitting with a MBRP, profab, or anything?
I don't recall the particular brands, but these have been installed with other downpipes and reported to us as not an issue.
I run the manifold and up pipes, with a drop in 72 and 3in down pipe. Don't know who's it is but it doesn't have the tabe where it would of bolted to the factory manifold/up pipe. The downpipe clears the up pipes just fine but does lay against the trans dip stick. I have had no issues thus far.
Joe what pedestal did you run that you were able to fit these in with the 3.5" downpipe.
We use either our fabricated pedestal or a cast pedestal with spacer. We would build the downpipe to clear.
Ok thanks...kinda what I figured. Guess there is a lot of massaging needs done if I want 2" with my setup
