What test pipes dont throw on the Check Engine Light? Is there a way I can fix it if i get pipes that turn the CEL on?

 

i would like to know that also...i didnt know that was even a problem

 

All of them will throw the CEL light some time or another , just have to install some Non-foulers and you shouldnt have a CEL light

that and i know like 03 and 04 350z , with just HFC dont throw them either.
hope that helps

 

Like Og Dave stated, they all throw CEL lights.

Non-Foulers should work but there are times where they have been unsuccessful. I've had my CEL on for 6 months. I haven't had time to install my non-foulers. (Drilling them was a bitch!).

i ended up buying titeks for 150 shipped and they come with a thing called an O2 bung with boss??? wht is that and the also sell a CEL fix for like $17, its like a bolt with a whole in the middle is that the non-foulers your talking about
