Hi all! (2023 G42 m240i)
I was curious on if a 300 cel high flow catted downpipe would be worth it. I am currently looking at the MAD catted downpipe for $900 that guarantees no CEL. Only reason why I am considering a catted downpipe is because I am on warranty until 85k miles and I wouldn’t want a CEL. I am running a muffler delete and CAI at the moment, and my main goal of adding the downpipe would be for more aggressive sound, not power because I obviously cannot get tuned, but its nice that the downpipe claims extra 30 hp. If anybody is running a catted downpipe please feel free to let me know your experiences! I just want to gauge if adding a dp will increase the sound noticeably or if I am better off not spending the $900 for the downpipe. Thanks!
