C63 W204 Power Increase Primary Cat Delete Only
Does anyone have figures for the power increase after a primary cat delete only with the secondary cats still in place? O2 sensor issue is coded out.
Is it worth to insert pipes into the empty oem cat housing to improve airflow?
I can only find examples with a full decat or only secondaries.
Many Thanks

I always wondered about this setup, if the secondary cats would help with the smell--- i like the idea, this is also coming from a ARH catless owner, my clothes all smell like gas lol
