If you don’t want to attract any attention, keep the rest stock. As others mentioned, secondaries will help keep the fumes down. I suppose you could always pay up and replace the secondaries with aftermarket hfc’s that are 100 cell but not sure you’d gain much.

I personally run headers -> y merge -> hfc -> 3” piping all the way back with combo of Magnaflow and Flowmaster mufflers (MF acts as resonator), and it’s still pretty loud. But for a 3” setup, doubt you could get it any quieter without sacrificing flow.
