3.3TT Deleting Primary & Secondary Cats (Stock Exhaust Otherwise)

[Hisham.Deeb]

Hey everyone,

I’m considering deleting both the primary and secondary catalytic converters on my 2023 Stinger but keeping the rest of the exhaust stock.

• Has anyone here done this setup?
• Will it make a noticeable difference in performance or sound?
• If you have a video clip or sound sample, I’d really appreciate if you could share it.

Thanks in advance!

IF you go that far, cause taking out the primaries requires dropping the engine . . .

I would just go full 2.5" or more out to the back. And, upgrade all of your pipes too. Also, you will need to get a tune to stop the CEL's from the CATs missing.

I went catless for my primaries and I didn't have to drop my engine lol. The studs tho can definitely be a PITA tho
