i called up a well known custom exhaust shop near me where i had a muffler and tails put on at. i was thinking of getting some high flow cats, because the super44 is nice but i would liek a little louder. anyway i call them up and he said they use OBd or something along those lines. anyways for 2 cats and labor im guessing he said $570. i really dont think the job is worth that much, i could be wrong, but could somebody tell me what i should be looking at maybe?
thanks
