What test pipes don't trigger a CEL.Or is there a way to prevent the CEL?

 

Preventing the CEL by not installing the test pipe is not the answer I'm looking for. That like believing abstinence is the best answer for teen pregnancy. It'll work but is just not gonna happen.

 

Tune is the best answer. Most of the tuning options out there can eliminate the CEL for the low catalyst efficency (p0420) that comes from test pipes or other forms of catalytic converter removal. It's a for sure fix, and you will most likely pick up a little power in the process, which can't hurt either.

 

I will put as much effort into this as you do. So far you are at zero.

my berk non resonated test pipes havent given me an issue yet.

 

Do the Berks have that O2 anti fouler? OkashiZ How long have you had them?

 

Also, on the ealier cars, (non-HR) they tend to be less sensative. My HR has given me a CEL with two different pairs of test pipes, both with some sort of fooler design (one had the J pipe extension, the other had a straight one). Lots of the DE guys can get away with it just fine with enough extensions to the anti-fouler.

 

What test pipes where they? I'm thinking I may just go HFCs...

 

Motordyne ART pipes come with anti foulers, no problems with CEL's here in over 1000 miles.

 

had my Berk Technology test pipes on since last april and no cracks, leaks, or cel from them. although i got uprev tuned a month ago, i still had no cels up to that point either.

 

You could have answered this question yourself OP if you took the time to read the Top 100 FAQ stickied at the top of the forum...
