| Accurate data is the key for a valid before/after comparison. Do you consistently run the same times at the track? To touch on your previous post: Track temp/conditions will be different (out of your control). Differnt NA Z configuration. Differnt mixture of fuel. Same weight? You didn't put on 5lbs or so since the last time you were at the track? The same driver will yield different results 99% of the time (we aren't programmed) Skewed data points to say the least.
Hopefully you didn't graduate based on being accurate? It's a good story to tell your wife or other folks thou:-)

Gary :I said I am aware of the debate about the "backpressure" blah blah blah... Glad you're paying attention.
:If you're happy with your setup, SWELL.
:Personally I think the ideal setup for the NA would be a Y pipe into a single 2.5" exhaust and muffler. Similar to what's available on the 350Z. Who knows, maybe Greg could make me something like that.
:All I know is my Z is running smoother. And without a doubt is making more power. Furthermore, she still rips off the line with plenty of low-end torque. If you ask me she had too much low-end torque to begin with. I like the slight trade off in terms of driveability and smooth delivery of power.
:If I had the funds (and maybe sometime in the future I will) I'd buy another set of pipes with new cats and I'm sure I'd still be happy with that setup as well.
:Afterall, my cats are OLD. 113,000+ miles and I can hear little bits of crap shaking around inside one of them (that can't be good). I don't know what a clogged cat would look like, but it wouldn't surprise me if mine were garbage. So given that I would like to run N20 in the future, I decided not to spend money on new cats.
:Is that okay with everyone?
