Cat Converter

[mtsoul]

I was just wondering if i can put a cat conveter on my apexi exhaust system or would i have to buy a stock exhaust system to put back on to pass inspection, and if i do need a stock system does it have to be from another gst since my car is turbo or can it be a regular one.. thanks

If you're referring to the N1 system, you can use the stock cat with the stock DP and the Apex'i "cat-back" But if you use the N1 DP, it replaces the cat with straight pipe. So

A: if you have the full N1, no, not without changing your DP
A, B: If you have the N1 catback only, yes
A, C: If you have a different Apex'i exhaust, I'm clueless
