honestly the change is so minute that it isnt worth it... its normally done when you get the whole setup done so its way cheaper for labour but even then the part itself is way over priced for what it is.....
if you want the same thing esp depending on where you about emmission laws so the cops dont bust you, is that you take the existing cat on the car and bang out the cement thingy inside.... poof instant hi flow cat that looks stock!!!
BUT heres the whole problem.... 95% of the time you take off your cat you will fail emmissions testing for sure... and the fines are not pretty.... but just so you know...
funny thing is tho... im taking my chances cuz i banged all mine out.. so when cops harrass me im like but look its stock!!! ahahah even tho its not really there.....
