Hello all new member here and just curious if a header for the 3.7 exists? before anyone responds I would like to ask how wide of a tire can I put on my kk. Thanks guys and gals!

JBA (not Jeepinbyal) is the only co I've heard if that makes/made headers for the 3.7. I think that was only for KJ's though so not sure if they'll fit a KK.

Tires depend on if you are at stock ride height or not.

The jba headers do fit on the 3.7 KA. So I would assume they would work on the KK.

To bad they stopped making the 3.7 KJ headers years ago.You may find a set in some stores stock but getting very rare.

Do these headers add performance or change the exhaust tone at all

Yes but only to top end power,you loose low end torque.

And yes/no for changing the tone of the exhaust,that depends on if your still running OE muffler or not.
