Hello, now my question is that do putting on headers with a 200 cell cet usually trip SES or EML lights usually? This is a mod that I plan on doing by next spring and currious if I should try the 2 stock O2 sensors or if it expected that I will be setting lights off then I would go for an O2 simulator right from the start. What do you think?

Thanks,

Yea, let's hear it!

Here's my take: I run an o2 simulator because I want my SES light to go on for a reason that I -don't- know about. I have a cat and can pass emissions, so the environment is OK. I can run a race pipe and not worry about a light. It's ideal for me.
