well i guess the title says it all. will i get a check engine light with the stillen exhaust or not. thanx ahead for any responces

 

does anybody know

 

No, you're safe.

 

mine hasn't caused the check engine light to come on yet.

 

nope........... it should not.. i've had my stillen for about 8K already.... no light!

 

Had mine for 7 months and no props ethier.

 

I have mine for over a year now and no peoblems.

 

shouldnt

 

Had for almost 2 years. No light. But Kinetix test pipes, yes. Wasnt supposed to on the '03, but I have it. Need to get a spark plug no-fouler on the O2.

 

nothing installed AFTER the cats will throw a CEL. the emissions engine light is based on readings from the O2 sensors. there are two located before the cats in the headers and 2 located on the cat pipes themselves.

even with my high flow cats and headers i didn't thow a CEL until i developed an exhaust leak at the cat pipe. from what i understand the computer expects a certain difference in readings between the pre and post cat sensors. with the test pipes the readings are identical, so it gets confused.
