Scooby, "why the concern?", as far as I know, GTR cats are already some of the best in the biz, Ben from racepace here in Melbourne is the bloke you should be talking to. he mentioned to me a mod he does to the stock gtr cats, where I think he cuts'em in half fits a 3'-3.5' pipe etc..anyway something like that. I was always under the impression cats only lasted around 60.000K's after that they're pretty much useless in restricting pollution.
