seemingly l have gained in all areas.......low end was like a rocket.....and no chugging....and l never drive with power key off

why should it have have been as bad as you suggest if all the previous comments said l would never miss it

Just a little humor with a mix of sarcasm.
Was just trying to make a point for those out there who think it will loose and drive like crap.

Brad i have not checked the feul economy but i would think if the car holds 14.7 AFR at cruising speeds i don't see why MPG would change.

Thanks Brad i will surely give it my all for that 10 second pass.
I'm using a friends 4.10's i hope the extra shift won't hurt my ET.
I'm still getting used to the 4.10's i admit they suprised the heck out of me at BG, how fast it was going thru gears.
BG was the first time i ran the 4.10's.
Ran 11.1 @128 1.69 60ft it was 80+* and very humid.

Too bad I can't remove my secondary system, since California emissions are very strict. I probably wouldn't pass emissions test if I did this mod. Same with long tube headers, Californians can't have 'em.

Ben:

While this is technically true, there are NO "CARB Approved" long tube headers (or short, or any other kind of header) available for the ZR1, nor has there ever been any.
But.....
However....
In accordance with Kalifornicate law, you cannot buy a "Used" catalytic converter. Period.
It's against 'da LAW.
Do not pass go, do not...well you get it.

OK, Ok, now were getting to the good part....
There are no NEW '90-'92 ZR1 exhaust manifolds with the catalytic converter integrated available from GM.
Zip. Nada. Big "0".
Haven't been any for years and years.

While you still must have all the original smog equipment, (air pump, tubes, blah blah blah), you can have headers and aftermarket cats, as long as the cats are 50 state legal and the headers have the air injectors in place.
You will need to make an appointment with the SMOG "Nazi" Referees and be prepared to PROVE that there aren't any more "NEW" exhaust manifolds/Catalytic converters in the GM inventory. (a note from a local GM dealer will suffice).
Be prepared to spend some time and that it likely will take at least three trips to the Naz....er...."Referee" until you finally get the waiver.

The '93 -'95's have removable Cats, and so they are screwed.
/Soup Nazi/ NO HEADERS FOR YOU!!! /Soup Nazi/.
