HEADER and CATALYTIC what's GOOD?

[559type_r]

i been thinking to get a JDM 4-1 header w/heatshield,,, but the problem is finding a 2.5" catalytic or test pipe to run with it to my stock itr exhaust system?..but to make sure my engine check wont light up because of O2 sensor... and ideal?.. i try sum 4-1 headers with a highflow cat, but that make my engine check came up..
the reason why i perfer the JDM 4-1 header is because it look stock and can fool the cop eyes, if i happen to get pull over and get my hood pop, i won't have to go through state ref and smog!.. yeah because, here in cali fresno, police hate imports!!! lolz.... thanx guys
