Unless some type of simulator is used, you will always get a CEL.

the mechanical o2 sim works perfectly!
ive had my test pipe on for over 1000 miles and no cel!
let me know if you need any help, the parts cost 5 dollars and it takes maybe 10 minutes.....

how is that test pipe working out for you? i am thinking about ordering one from comptechusa.com, but its $250? kind of expensive for a piece of metal! where did you order yours from?

JDM S2000

yeah 250 for a piece of 4 dollar metal is a lot
I got the megan racing one for 89 shipped and it has a resonator

Berk has a group buy right now. 99.95 shipped, however most people have had success with the built in 02 fix however I throw a cell after a couple of cycles. Maybe it has to do with me being superchargerd dunno.

berk pipe. $100~. no CEL after about 2 years and about 5k miles.

comptech has an 02 delete for $130...could i buy the berk pipe and use the ct cel delete with it im assuming yes

The berk pipe comes with the extension for the o2 so nothing else is needed other than jus that pipe.
