Catted downpipe??

[Drnick]

Yes, I know, do a search, but I need new/recent comments and advice on this, as there are so many new DP’s available now. Which one Doesn’t show a CEL??? I have simple mods, just an CAI and exhaust. Thx

Every answer you get will be biased, as is mine. MAPerformance. Right price, no CEL, fitment was perfect, GESI cat, sounds fine. idk. I can't really comment since it's the only DP I've had, and I don't care about how the car sounds, I just want to go zoom zoom down the track for a few seconds, then eat cookies with @puzzled and @ikeaboy

Active Autowerks. Couldn't be happier with sound and fitment. No CEL.

Theres an AMS catted DP in the classifieds. Might wanna try that one. I can tell you the MXP catted and CTS catted ones will throw a code.

Thanks for the info, do these cats have a flow rating of some sort?

Only one thats a no CEL guarantee is the active autowerke one. We have them in stock.

Active Autowerke, CG precision, Fabspeed, ETS & Akrapovic all do not throw a check engine light

Ok, can anyone either dispute this,or support this? With actual facts.

There was a forum poll a while back, but I can't find it. Any GESI catted DP should be fine.

The facts are pretty simple. O2 sensor on each side of the cat, if the cat is doing it's job, you won't get a CEL. This means any DP using a GESI cat should be fine.

DUDE DO A SEARCH. I'm kidding. I do the same thing. Been running the AA catted downpipe for quite some time now and no CEL. I push the car hard (track, autocross, and road) and have other mods that would make a CEL more likely, as well. It's a great, high-quality part that produces an excellent sound and gains. Highly recommended.

Honestly, it is worth searching because the main options will not have changed much from 2020. XPH's list looks right to me. I have had the AA catted downpipe for a few thousand miles and no CEL. I am very pleased with it.

I will say that I do not see the point of paying extra for a catted downpipe that still throws a CEL. If there are in fact a bunch of new options on the market (I'm not sure there are), here is a rule of thumb: unless the manufacturer guarantees no CEL, then it will probably throw a CEL at some point eventually.

Also, I would not concern yourself with flow ratings or 4.5" vs 5" or w/e because the difference is negligible. The main distinction will be between catted and catless, and even then it is a ~10-15 HP difference, which I am not sure any of us could reliably detect.

I'm telling ya. MAPerformance says no CEL and there's no CEL. Untuned, 4000 miles on it.
