I feel like I've been posting a lot lately haha but anyways, my current setup right now is the Exceladyne downpipe (deletes primary and secondary cats) and the ISR single exit. I like the sound but it could be a possible problem with how strict things are getting here in CA. I've thought about an electric cutout but I would obviously need the stock cats back on or high flow cats for it to actually have a purpose. If I went back to stock cats and put a cutout in, I lose the nice gain from being catless with the BR tune (now gencoupestore). I also might not like how it sounds with the cutout. If I went to high flow cats (more money), then the tune might not be compatible. I read on another thread that the BR tune doesn't have support for high flow cats.
Another option would be to just weld in fake cats on top of the downpipe in the case of being pulled over. I've already put on an AEM intake since it is CARB legal vs my previous K&N. The fake cats wouldn't help the sound though, unless I got real 3in cats and had them hollowed out, so they would essentially be resonators.
