MACs 1 3/4 + ORY are in Well, installation was straight forward, had to remove the starter to make it easier (Also wrapped it with Heat Shield as a precaution).
Removal of the back manifold bolts on the head were a pain. Removed air and capped the EGR tube. Ory fits nice, no rattles.
Had to plug all 4 O2 bungs as my Z has no O2 sensors.
Upon startup, I was shocked that the MAC's/ORY were quieter with Hooker catback, than stock manifolds and no cats. No more rasp. Just a nice mellow tune untill you floor it. Can't wait to take to the track and uncap the cutout.
Car felt more responsive and quicker. I'm happy with the choice so far. I know you will post "why not LT's?". Well, I has to do with, "I couldn't pass the price". They were a B-day gift from my little Bro.

Well got it dynoed 334rwhp and 318trq with open cutout.
before was 315rhp/304trq so thats a gain of 21rhp and 14 trq without tuning.
I'm pretty happy with the results. Is a little rich.
