The Random Tech high flow cat that McNews sells.... does it take the place of both the stock cat AND flexpipe. It looks big enough to do so, unless that's the wrong pic. Thanks.
It connects to the stock header and the stock flexpipe. It can also be fitted to aftermarket header & flexpipe, but to my knowledge it is a direct replacement for the OEM catalytic converter piping. This was the best buy for my car yet.
