I looked up my hood this is what the emissions sticker says: This vehicle confroms to U.S. EPIA NLEV Regulations applicable to gasoline-fueled 2001 model year new LEV passanger cars and Cali Regulations applicable to gas-fueled 2001 Model year new Lev Passenger cars.

I am looking at the cattman y pipes 1 is with federal emissions and 1 is CA or 50 State emissions? Which 1 is better for my car?

 

I'm pretty sure in 2001 all of the Maxima's were CA emissions

 

should be ca emissions, look in the stickys to double check

 

Ahhhhhhhhhhh lol wow are serious???

Learn how to search or go to next page and look at the forty thousand other threads about y-pipes.


lol are people just getting dumber dumber here????

 

you should just get cattman headers... that comes with the y-pipe and its probably the best things out for your exhaust...
