R/T Hi-flow cat problems?

[Prelude707]

I was looking into a Random technology hi-flow cat for my 2000 Prelude when I came across this review and was wondering if it was true:

Unfortunately after doing research, some vehicles equipped with OBDII systems ('97 and up)have problems with high flow cats (Note: this applies to ALL brands of high flow cats, not just Random Technology) being too free flowing causing the O2 sensor(s) to trip the check engine light with the P0420 code. It will pass emissions fine; however, your check engine light will always be on which can eventually cause other problems because the computer will be trying to compensate for the problem. Nevertheless I still highly reccomend this product if your model vehicle hasnt had a history of this problem when equipped with an RT cat, just ask the guys if your particular model car has had any history of my problem with the check engine light. Random Technology is constantly developing and improving their products so the guys there will know.

just do the OBDII workaround and you'll be fine. that review does make some valid points. in OBDII mode, my check engine light will flash on after a few minutes of driving and it's the O2 sensor that sets it off. i have the carsound high flow cat.

basically...install a switch between the ECUs backup power line and the ECU, when the switch is in the off position...your ECU will reset everytime you turn your car off...if its in the ON position...it won't clear
