Question for owners of catted DPs

skier · 11-25-2009, 10:58 AM

If you have catted DPs installed, no O2 sims, are you getting any CEL's?

Post the production date of your car, tune - if any, and make of catted DP's.

Production date and software revision if you know would be a great. Interested to see the results of this!

This sounds like good info as well - let's hear from some 2010's!

I had cel with my catted AR dp's, my car is pre 29,2.....manufactured 26/10-2006.....And i know it because it throwed catalytic converter codes....after installing o2sims no cel's what so ever....

I have AR catted, running Procede RevII with the o2 sim not engaged, and I have never thrown a code in 6 months. I am pre 29.2 and build was 4/2007.

by the way im catless now and i love it......So if your about purchasing ar's do the catless ones with o2sims for maximum boost and power....

I would love to go with catless DPs when I receive my car - but I have concerns regarding CEL w/ it being a 2010, even with 02 sims.

Yeah - this is what prompted my question. I want DP's, and would pay extra for catted if they prevent CELs. Putting O2 sims on top of catted DP's increases the cost and reduces the gains, but it may help in reducing emissions (although no vendors to my knowledge make specific claims in this regard).

if you have 27.xx software....want to get catless DPs..My question is with the RevII and its built in O2 sims, will I be able to pass inspection from a state that uses the OBDII...I want to go completely catless, but don't want to deal with not being able to re-new my inspection in July 2010....What you you guys think?

do you guys pass the two year registration inspection with o2 sims?
