i have never been one to optimize timing. always go conservative and then add boost to the edge of knock.

LOL, I like that style. It's not a lack of timing, it's a lack of boost.

What does the stock exhaust look like on the 1500HD? Is it the duals back to the muffler and then one big tailpipe out the back?

If so that is not a bad exhaust at all. It's what was on my SS and it never really felt like that much of a restriction with the LQ9, Radix 7.5-8psi, longtubes.

One reason I say that I never really felt it was a restriction is that my truck went 13.2 on 7.5psi and longtubes basically. I'm sure a freer flowing exhaust would've picked up some but, at that level I didn't think it was worth the louder noise.
