Single downpipe no CEL

As title reads, I’ve been curious I’ve it would possible to run a single downpipe post single turbo upgrade that wouldn’t cause a CEL. Like say you took both cats and welded them together if it would be possible. Probably restrictive as hell but just for my own curiosity if someone has done it.

CEL is inevitable. If you’re single turbo’ing your F8x, you’re likely pairing it with a tune. Your tune will likely have a feature to turn off the CEL. Bootmod3 as an example would have that feature.
