For those of you who are curious about hi-flo cats, here is a comparison of my car from basically stock to BPU:

2000: 47,000 miles, TRD catback, K&N drop in, 300 RWHP on 90+ deg humid summer day, driven right off the street to dyno, no tricks, pump 93.

HC parts per million (PPM)---> 0 ppm out of allowable 120 ppm
CO %---> 0% out of allowable 0.67
NO ---> 1 ppm out of allowable 848 ppm
CO + CO2% ---> 14.2%




2001: 61,000 miles, BPU since 48,000 miles

RMM downpipe with hi-flo cat, Blitz DSBC (turned off), BCC

HC ---> 25 ppm out of allowable 120 ppm
CO % ---> 0 % out of allowable 0.67
NO ---> 36 ppm out of allowable 848 ppm
CO + CO2% ---> 14.7%


Piece o' cake! :cool:

As convenient as this is, I am thinking about having a shop make a straight pipe section in the future.............of course I will always have the cat available too.
