High Flow Catalytic Converters?

[repin_LB]

Well i just got my G recently and im starting to get excited about fixing this beast up. So far i just got my JWT pop charger and z-tube installed and was thinking about maybe going for a little more sound and performance But how do you guys feel about the HFC converters? i hear they are on the border or legal emission levels or something?

I'm a big fan of how they sound and this is my next upgrade. I've been looking into the Berks and Random Technology. Suby just had some stillens installed and has been throwing some 02 sensor codes.

Been told by some companies that this is the biggest gain bolt on for our cars.

Hey there and Welcome to NICO!

There was a discussion about this recently, it's quite the same with any catalyst modification If you are out of warranty you can go for it. Just make sure it's legal to modify emission control devices in your state. I don't know what the California laws regarding that are.
