that's a loaded question.

there are the exhaust manifolds from the 09-10 Jeep manifolds actually work but tight. see this thread on for a bodies only. https://www.forabodiesonly.com/mopar/threads/73-scamp-5-7-swap.423219/

TTI is going to be the no brainier but get ready to spend a load of cash I went tti way non coated then did my own ceramic coating spray on and so far they are good, they fit awesome with Manual steering. but get ready to spend a few hours putting them in. Its a [censored] bolting them on after the motor is in the engine compartment. if you can and have the means drop the front k- member, assemble the motor and trans with headers then reinstall. if you cant do that its ok you will just be bending and using swear words you never new. its fun but takes time and patience.

there are a lot of options with TTI that's why I said loaded question. see link to TTI
