yes but what do people do with crawford!!! and what does R/T stand for newb question if so dumb =\

 

Random Technology High flow CATS......but I have them in my G35 and I passed VA state Emission. I like it but there is some bad feed back about the CATs collaped on FI cars...and I don't know what people do with their crawford CATs.... I am saying this from my experience

 

I don't think you're getting much of anything, other htan a placebo effect, for paying 500-700 for the 'higher end' cats like crawford or random. I've read just as many positives and negatives for them as the 'lower end' ones like kinetix. i've seen just as mnay people having fitment problems with kinetix as crawford, and helix and random........

Just like the y-pipe - only a tard would pay $900 for a y-pipe on a G35 when a $100 will do exactly eh same thing.

because the stock exhaust is pretty good; the headers, stock cats and stock y-pipe are where it blows.

 

would it pass ca smog

 

Ive had kinetix HFC's on my car for two years, love them. They also passed CA smog with flying colors. Also no rasp at all when fully warmed up.
