Usually no pictures means it didn’t happen so in this case I know need a sound clip to justify. I’ll try to get to it this week.

Some forum member say 200 CPI delete doesn’t sound or feel much. For my case with resonator delete and OEM mod done first it was noticeable. It think it’s all about the package, alone probably not as much but with more flow and less restriction together you could feel and hear it. I left primaries alone since I wanted some back pressure for acceleration, since I don’t do much 200-300km pulls and I didn’t want o2 warning lights. I had a Tune already so it’s enough for now unless I go ESS then the primaries need to come out.
