as you have probably heard in many cases you get what you pay for
i have a china cooler and im not happy with it
i plan on upgrading to a good quality one in the future
then again any FMIC will be better than the stock side mount
with the cat
take it out and get a large screw driver and a hammer
put it back in, looks like a stock cat but has no restrictions
if your set on getting a certain exhaust
dont settle for second best
you will always wish you bought the one you wanted..
get one of the apexi power intakes
if nothing else you get the cool suction noise
