Ok so I have come to terms that my cat conver will need to be replaced eventually. The engine light comes and goes as it feels. I was wondering since I'm going to be paying 2k+ on new converters I mine as well as pay around the same for a whole new exhaust system. I was wondering if anybody knew where I can get a whole new system with the cat converters. Please post links for where I can order something.

CAR INFO:

Car Type- Infiniti
Car Model- G35X
Car Year- 2007
Engine Size- 3.5L V6

Stock single split exhaust is on it as of now. Also I live in Canada Alberta so I don't need that mumble jumble California emmisions catalytic converter bull. Thanks guys.
