Single tip Vs. dual exhaust
I've heard from a few different RX-7 gurus that single exhaust systems provides far more power than a dual setup. Is this true???

Dual exhaust it is then. Gotta love this site! I will completely take out my fact. system and replace it with a dual setup. Not sure who I'm gonna go with. And when it comes time for the good ol'e inspection, I will just do a temporary swap back to the fact. setup...just for looks he he. Screw three cats!

No you probably won't actually.
There are so many other variables when designing and building an exhaust system, that unless you build two systems using the exactly the same type/brand of mufflers, to exactly the same standards of construction and design, and tested on the same car, you won't have conclusive proof of anything. The size of the pipes is another factor that's far more important than dual or single layout.
These are the reasons if get pissed off when people make the ridiculous blanket statement "single flows better than dual". That's like claiming a 6-cyl motor always makes more power than a 4-cyl motor. It ignores dozens of other more important variables.

the 30lb difference i've seen quoted over a stock system is enough to sell me. that is if my ears aren't pouring with blood at the end of each day.
what's the weight diff between steel and alum. hoods?

Please feel free to post pictures of a competitive rotary-powered road race car, as I would really like to see one.
