Yeah turbo's are technically mufflers since they take some of the exhaust flow to spool themselves, But i still have my two cats on so i think it shouldn't be too loud compared to a 135i. Im supposed to get it monday, hopefully i have time to work on it before the weekend to get it mounted up. praying its a direct bolt on
