I've recently acquired a 2006 350z with an APS twin turbo kit. It also has an APS 2.5" exhaust kit that has test pipes on it. Since I would like to use it on the street and register the car, I have to switch out the test pipes with some cats. Plus I really hate the smell that comes off the car with no cats.

So, my question is if I wanted to install cats, are they all the same size? I'm hoping that I don't have to find an APS one because I guess they no longer sell to north America. Could I buy a set of HFC, like Stillen, and have it fit with the rest of the APS system?

Sorry about the newbie question but I don't know much about exhausts other than ones that you buy as a kit. Thank you for any information you can provide!

Much cheaper and better for power to weld in a universal bullet cat downstream (either in the Y or even further downstream). The further down, the longer it will take to heat up and start working, but it will be less power hit with the turbos. You can get a pair of 3" metal cats for under $300 (100 or 200 cell) and probably $100 to get them welded in by an exhaust shop.

Thank you for the information! I'll do a little research before pulling the trigger on some cats.

Test pipes and catalytic converters are interchangeable. They are designed that way.

nice z! what bodykit is that?

Thanks! It will be nice when it's running. The body kit is the Tourenn kit and spoiler. The fit and finish is kind of meh.
