removing the 2nd non sensored cats makes a big difference in throttle response with my 01 S with egas. The throttle response is awesome now and the sound is pure sports car music.

Ill have to climb back under the car and check. Do you bypass the cats on the headers or the ones right behind the mufflers? The only after market headers ive found all have no cats, but a hole for an o2 sensor.
I only meantion the drone as an informational tid bit in case anybody is interested in the same muffler. I barely notice it.
