cats are known to rob some power but i dont think they are steeling quite that much...i think a leak down test is a must..Good luck on your case of the missing tq

Taking the high flow cats off ended up being worth 8 rwhp and 12 rwtq.
The final numbers on the car were 432/386 with the cutout open.
I ran it at the track last night on motor and it trapped a consistent 3-4 mph than before the heads, rockers, and cat removal so the power is all there.
Figured you guys would be interested in the real world results to back up the dyno gains.
