Catted DP on xi with no CEL

Tbordeau · 05-23-2018, 09:26 PM

Hey all,

Looking for the best catted downpipe that won’t throw a CEL, 2011 E90 N55 xi. I have Dinan stage 3 software in it so programming out O2 codes isn’t an option.

After some research it seems like Wagner or AR catted would be best, anyone have experience or know of warranties that would help me decide what to choose?

Thanks!

I've got about 3k miles on the Wagner with no light but I don't think they guarantee you won't get one. I could be wrong.

I threw a light with my Cobb catted downpipe

If you want no Cels use an OEM BMW downpipe.

Even my high flow catted pipe throws cels.

The 3 most popular catted DP options are VRSF, Wagner and AR.

VRSF is life time warranty.

Wagner is 2 year warranty.

AR is not explicitly mentioned.

If your only concern is a light on the dash, couldn't you just get the dp fix?

Not sure where you are in the world but are their any other things you need to consider in order to get through a regular check?

Some aftermarket catted DPs are hi flow which usually means a different cpi. It may not generate a cel but may impact other things which you may then need to address.

How the DP looks may also need considering. For example, in some places, one of the checks is a visible inspection to see if the DP cat can be seen. As long as it looks like it has a cat, it passes that part, even if it's a c'less DP

off topic but where did you get your dinan 3 tune? is it worth it and what mods do you have (oil cooler, etc.)?

dleccord, I'll answer for him. Don't waste your money on the Dinan. Go with MHD for whatever hardware you currently have and eventually will aspire to. Less money, more power. And safe. Before you ask, my opinion is valid as I have been through the Dinan power upgrades (stage 2, then 3) as I wanted to spare my CPO.

Did you need to upgrade your oil cooler?

Johnny Boost · 05-25-2018, 08:47 AM

Is he really going to gain power from adding a catted downpipe with a Dinan tune?? Doesn't seem like it would be worth the $$$.

Toome · 05-26-2018, 03:36 PM

There's no point running an aftermarket dp with a Dinan tune

You can run a stage 3 Dinan tune without an oil cooler. People do it all the time. I had mine installed at the dealer. Dinan has dropped the price on their software by quite a bit sometime over the course of the last year.

Tbordeau · 06-03-2018, 06:50 PM

I ended up going with Wagner since they seem to have the best track record of no CEL. Will install next weekend along with Corsa exhaust and Cobb FMIC.
