I finally sorted out a fuel issue that was hanging over my head last year, so I put my car on the dyno to see what kind of power it's making. I ended up running 305whp at 13psi
I also ran 285whp on wastegate pressure 10psi with the full Avo 3" catless exhaust into a Perrin 3" non resonated
For reference, the other line on the chart was from last spring. 10psi (Before the fuel issues) but with the standard 2.5" exhaust setup. Obviously there could be some discrepancies in ambient temp etc, but there are definitely benefits to opening up the exhaust from the downpipe back
