yeah, on a 02 WRX with three cats including one pre-turbo, just cutting the cats out got you relatively major gains. that's apples to oranges though, since his FRS doesn't have a turbo. surely on an N/A car, the piping diameter, bend radii, and merge collectors play an important role, moreso than just cutting the cats out of a stock manifold.

it just seems troubling to create an exponential increase in the car's emissions for an incremental bump in horsepower. maybe if you're running E85 all the time it's not a huge deal. idk.

There we go, that's the knowledge right there.
