Hi-flow cat & test pipe

i just read one magazine, import tuner issue Oct 2006, topic about high flow cat and decat. they used 1999 Civic SI to test the difference between stock cat, 2 high flow cat and 'test pipe'(decat).

using stock cat
147hp, 105lb-ft

using magnaflow ceramic core hi-flow cat
150hp, 107lb-ft

using magnaflow metallic core hi-flow cat
151hp, 107lb-ft

using test pipe
152hp, 108lb-ft

conclusion, decat and hi-flow hp difference onli like 1-2hp, reduce 10pounds will do loh to get the gain back rather than harming the environment.
