Exhaust: When to upgrade? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

In its simplest form, At what power level should I look into upgrading the factory exhaust. I want to keep the car as quiet as possible without choking the exhaust flow. I already have Tomei EL headers, but anything behind that is what i'm talking about.

I would like to keep the secondary cat due to emissions, since the tune I currently am using from Moto East isn't giving me a CEL.

This car will see a Kraftwerks C38 Supercharger kit at some point in the coming year, so i'm doing my research before hand.

Next best thing would be to get a high flow catted front pipe. It'll give you the most power, considering you've done headers already. Car will sound meaner, and just a tad louder.
