Alrighty then, here is what went down. Got the Z back on the road tonight. First I reset the computer then did the install (Normal proceedure for myself). Im pretty good at soldering now, lol. From my experience it took a while for the computer to respond (Compared to Berks HFC's). I think in my experience that it was because there is so much less back pressure in the exhaust. Car never had a CEL but did have a hard time at idle for a while. The more I drove it the better it got. From 5 to 75 the car has so much punch. It is like night and day. The clutch engagement is smoother do to less torque(back pressure) at lower rpms. Does this make your car louder? Not in my opinion. At idle it is very quite. It seems to flow so free that it struggles to idle a tune. At higher rpm's it does seem to have some rasp. Or I think. Sounds like someone dropped redrider bb's in my tailpipes. We'll see after I get some more miles logged on. I always use Z1's anti foulers in my secondary 02's as well.
