be careful how much you pay for one because sometimes they rip you off because they are somewhat rare...
i found ebay borla replicas for 239 shipped to my door. i also heard that the ebay replicas are actually better than the real thing
theyre about the same. the borlas got a bad name because the old ones were ceramic coated, and they tended to crack. the new ones (V4) dont crack. the replicas however have a weakness too.. i just cant remember what. either way you will be happy. call me up if you want anyone to BS with while installing them. its been a while since ive done work on my car heh damn subarus being soo reliable n stuff (jk)
