How do they know what kinda pipe to send me. LIke isn't there a cali spec and us kind of pipes? I bought it of of ebay and payed with paypal. just curious.

 

might want to ask the seller that

 

"All we need to know is the year of your car and if it is a 1999 or 2000 if it has FED or CA emissions, best way to tell is look to see if you have an o2 sensor behind your main catalytic converter (if you do it is a FED, if not it is CA emissions). Not sure, we'll help you figure it out. "

 

my 1995 have O2 on my cat, therefore i have a FED.

 

also for that 99.5-01 look at front of spark plug cover if there are 4 sensors its cali 2 is fed

 

So a 98 or below are not cali spec?

 

any other ways, I have a 97
