Best Catted Downpipe

[SaeJPark]

Just wanted to gather thoughts I’m looking to purchase a catted Downpipe (one that has no CEL) and am contemplating between the AA or the AMS Downpipe. Or if any other companies have one I don’t know about im open to any suggestions!

Just installed an AA catted downpipe and it performs well. My 2nd choice would have been the MST catted downpipe.

I went with SHS Autosport and got the exhaust too. I figured why not go full 4" instead of buying a downpipe and exhaust that shrink down in the middle.

Went from catless to Active Autowerks and it’s great. Very happy with it.

You're going to want something with a GESI cat if you want the best chances at no CEL. AA and MAP are two great choices.

I definitely recommend the AA downpipe. Super popular catted option and I have never heard of anyone getting a CEL with it. Also it sounds amazing

Like a broken record I have AA and it’s fine. I also have the EOS catback and I like it, for the money you can’t beat it…

I have AA and its great.

But to be truthful, there have been bad batches of AA that did throw CEL. The warranty is on the Cat and not the work. So pulling it on and off is on your dime. Some member was snake bit and had it happen a couple of times. And there was question as to the Bimmer Code crowd who turn on Sport+ and how that interacts with AA cat. But Sport+ not recommended the A90 so I'd code it off if you've coded it on.

None of this is unreasonable for a product like this.

The best option is the Active Autowerke catted downpipes

AA is the best downpipe by far, hundreds sold with no issues!

We have them in stock and on sale.

I have the AMS Catted no cel

AA dp is the one I would like to go with hopefully soon since it has SO many good reviews!

Is there a DP which improves throttle response while being quiet? I already have an AWE exhaust I don't want more noise but I do want the car to be less numb / laggy.

AA
its got 400 CEL vs 200 CEL with other catted options

you sill get all the pros without the obnoxious sound increase

Surprised the CG Precision DS-1 hasn't been mentioned. That's what I landed on.
