I am wondering does anyone here know that if I want to install two headers on my IS350. Is there any sensor or check engine light prooblem which I need to get fixed after the installation? Maybe O2 sensor? Thanks.

 

Exactly whatt headers are you getting? Some come with an eliminator to get around that issue.

 

I am not sure the brand. But they are stainless steel headers. I am just worry about the check engine light.

 

As far as i know only PPE header work great on is350. As long as it installed correctly you wont get a CEL. I have the headers with HFC and no issues.

 

PPE headers enough said.

 

Ok, I will make sure. Thanks.

 

Do you have any online resource for purchase?
