I don't think so, there's no sensor after the second cats. Full delete won't even throw a code.

why would you delete the secondary cats to add more cats?

Just delete them and do an x pipe

Hey guys,
so yeah, I didn't add more cats. I made it straight instead of X pipe. And just done it today. Well, it sounds cool on high rpm and stay quite at low rpm. And yeah, no check engine light was on.

i don't know if there's any significant power gain. Well, I don't think I can take any picture of it. But let's see if later on I decide to make a custom smaller resonator, I might be able to share the picture for you.
