ok, im doing a custom exhuast on my 2000 dx coupe with a fairly stock y7. so i put a header on it which takes out the stock e/m / cat..now im using stock si piping with the stock resinator and everything. now my question is, is there a certain location a catalytic converter HAS to be, or does it just have to have one? Do i need one to pass va state inspection? any help is greatly appreciated

you need a cat to pass the visual inspection and then emissions.
not sure about the placement, pretty sure where it was originally might be a good spot

he cant put it where it was originally due to the fact that originally it was made on the header..

op, put it after your down pipe flange.. basically at the beginning of your mid pipe...

the problem with that is, that is where the stock resinator is?

...for SI, there has to be one. weather it works or not, not my problem unless you are in an emissions checking area, north VA, MD etc. i dont really care where it is, preferred is up where the exhaust is hottest, gets working faster.

take out the res. and put in the cat

well im just throwin in a cheap ass straight thru cat, nuthin actually usefull, just to pass the visual check..we dont really have emissions either...but i still need one to pass the visual check..i might just take out the resonator and put it there
