Catless DP Only?
Is anyone running just catless downpipes, with no tune?
I know for sure it will set a CEL/MIL for o2 efficiency.
I'm curious if anything bad will happen, and if there's any performance gains.
I want more noise out of my exhaust, and am thinking about doing a tune anyway once my engine is broken in.
So I'm thinking of skipping deleting the resonators and just going straight to downpipes.

I had catted Rado downpipes on my 2014 CLS63 and loved the sound. It was noticeably louder but not obnoxious. Watch some videos of catted ones first, it might be loud enough without CEL issues.
