A. The engine air filter element may be removed or replaced. A replacement element which is taller than standard may not be used to hold the air cleaner cover open. No other components of the air induction system may be removed, replaced or modified.

E. Any part of the exhaust system beyond (downstream from) the header/manifold or catalytic converter, if so equipped, may be substituted provided the system meets the requirements of 3.5. Stainless steel heat exchangers are permitted only if the physical dimensions and configuration remain unchanged. Modifications of any type, including additions to or removal of, the catalytic converters, thermal reactors, or any other pollution control devices in the exhaust system are not allowed and the system must be operable. Replacement catalytic converters must be OEM if the vehicle has not exceeded the 5-year/50,000 mile warranty period as mandated by the EPA. Converters must be of the same type and size and used in the same location as the original equipment converter(s). This does not allow for a high performance unit. If the vehicle has exceeded the 5 year/50,000 mile warranty period, replacement catalytic converters must be OEM-type as per Section 13.



I can't really get the words through my head, but to what i understand is that you can only have a drop-in replacement for the stock intake, and exhaust maybe replaced? or is it that i can have a cone intake + exhaust? let me know.

thanks in advance,

Basically you can only use a stock replacement filter like a K&N filter.


The exhaust is free from the cat back.

 

thanks

 

I had the airbox on my eclipse all hacked to hell with a cutoff wheel and they never said anything about it

My place was pretty lax tho. Also, the ecipse 1.8L non-turbo runs in H-stock, the slowest class there is. Not exactly a hotbed of competition. I was usually the only one in it. My victories include some lady in an old Golf and an old guy and his wife taking turns in an 80's Lincoln Town Car(!)
