If your going to mill the heads past 0.030", you should also get the LIM machined to match. When people go past 0.040" on the L36 they machine the LIM.

thanks alot for the info- believe me im writting everything down.
I figured there would have to be modifications to the rest of the block, "if you take a bit
from here, gotta take a bit from there too." so it equals out.
thanks a bunch man.. i will keep everyone posted.

nice bandit... cant wait to hear it. also we might be able to help each other out on future fixes, since we have cousins

It depends on province. I know BC doesn't require them, but Ontario does. Dunno about Quebec.

I wouldn't delete it anyway. I had one off the SLEeper for a short period (bad cat, new one wasn't here yet) and it lost some obvious low-end bawls.

Emissions inspections are one thing. In the States, even if you live in an emission-test-free zone, it'* STILL illegal to run without a cat. Federal Law, all 50 states.

Yes it is illegal.
we have police looking around for modified exhausts.
you get a ticket.

The problem is that you cant pass inspection without one.
But BB doesnt have to go for inspection till 2014, because the car passed inspection
before i bought it.
The tints i ordered a while back got here a while back... its 35% front and 5% back (snaptint.com) im not too woried about passing inspection.

its ok I will do more reasearch,
everywhere i look on the net.. it says its a small increase, because it "free'*" up your
exhaust make it flow more. But pressure is required as you guys say..
phaaaaaaawck... i really have to do more research..
a highflow cat from the parts store
is around 90$.. dont know how much a magna will go for.. its not much $$$ but if i can save on anything.. i will go for it.. seein as how im going to dish out serious cash for cam
and tranny work.

thanks guys
