High Flow Catted DP
So I'm trying to get to 500WHP w/ my 2020 M340i and was wondering about catted DPs. I'm going to be tuning my car so I can remove check engine lights, aside from that light is there any reason to go with something like an AA DP versus a CTS turbo DP? The AA might fit slightly better but I don't think its worth spending 3-4x as much but I'm trying to get opinions here.

The AA DP is really appealing to most on here specifically because it guarantees no CEL, so us non-tuners can have our cake and eat it too. But since you're tuning anyway, your options are pretty much whatever you please.

Yeah I get that with the people who have the locked ECU or are still under warranty and don't wanna void it. CEL won't matter, I'll clear/code it out once I figure out how. I just wanted to make sure there was nothing else I was missing. Thanks

If emission testing and check engine light are not a concern, there is no reason to pay extra for downpipes with GESI cats. The standard, less pricey catted downpipes will work.

The car will run normally; the check engine light is just a warning light that you can ignore.
