What are you doing on the exhaust side?

Hi Paul, You’re welcome! For the exhaust I’m currently running my 2004 stock headers w/stock primary cats, Fabspeed mid pipes and an FVD Brombacher Sound Version muffler. Way down the road I may try 200 cell headers/primary cats coupled with an IDP plenum and 996 throttle body to take better advantage of the increased displacement (if I can keep it emissions compliant). In any case I’ll keep the Fabspeed mid pipes and Brombacher because they’re perfect for me.

Frankly, I probably will never proceed with the header and plenum upgrades because I’m very happy with the current performance/drivability even with the tight engine and break-in tune. Can’t wait to finish initial break-in and load my custom 93 octane tune.
