Ok so i have 95 z28 6 spd. it has a flowmaster cat back and a K&N CAI. I live in california and i can pass smog. my question is would i be able to get shorty or mid length headers and a ORY and still pass smog because i have heard that i can't get LT headers? or would i have to get a high performance cat? im not too familiar with exhaust systems but is a high performance cat and a ORY in the same place? (as far as function). also what else is their to an exhaust? i hear people talking of midpipes and im not quite sure what they are talking about. thanks for all the help i really appreciate it. im sure i sound like a real car noob.

 

in calf u will need dot aproved cats so u will need to check and make sure they are approved in calf and have the proper carb number. and i believe u are right lt headers are not legal in your state. get the mid length headers they have a little better flow than the shorties.

 

The mid-pipe is the section of tubing between the cat and the rear muffler that usually have a perpendicular connecting pipe or the pipes temporarily merge. This is to equalize the pressure in both exhaust pipes and keep the engine back-pressure as low as possible since back-pressure kills your high-end power.

 

^^^ also called xpipe. and the ory pipe is a off road y pipe that does take the place of the stock y pipe and cats and is not legal in calf on the highway.

 

Or hpipe in some exhausts

 

ok so i would need a high flow cat and mid length headers? do those hook directly up with nothing in between them?

 

yes they should all hook up to the stock exhaust. also should hook to any cat back exhaust should u have or wish to have one.
