Kooks Stepped Headers

Does anyone know if the stepped headers will bolt up to Solo HF cats or do I need Kooks connection piece with their cats? I ask because I do not see Kooks offering a 3inch connection piece... Only a 2.5inch with cats

Currently, I have a 3inch SW catback exhaust with Solo HF cats.

I'm betting the inlet on the SW catback is 2.5". You'll need either cats or off-road connection pipe to go from the KOOKS to the catback.

You won't be able to use your Solo HF cats with LTs.

You would need Kooks cats. Kooks can custom make a 3" all the way through one, it just takes time to special order.
