so i just buy a injen intake and a warspeed y-pipe to install on my oem exshaust system(fed emission) ...so i wanna know if i will need a 02 sim to keep my s.e.s light off????

and also if ive make a great move to buy those part to improve performance??

 

with the y pipe u shuddnt get a check engine unless u remove the pre cats or the cat right after the y pipe

 

tanks.....!!!!i was scared

so i hope with this little mod that i will be able to spin the wheels without water
