Welcome to the description, where you will always find more about the video and the things in it.

I installed a Flowmaster Super 40 Delta Flow: https://www.amazon.com/gp/product/B00...
And a new tailpipe from Walker Exhaust: https://www.amazon.com/gp/product/B00...

The Cherokee uses 2.25” exhaust pipe. I picked up an extension piece and clamps from a local parts store.

THE TOOLS: -Sawzall or hand saw
-Various Sockets
-9/16” Ratchet Wrench for clamps (XJ uses 2.25” exhaust pipe)
-Muffler, Tailpipe, Extension piece & 4 clamps
-Front Tailpipe Hanger: https://www.rockauto.com/en/moreinfo....
-Rear Tailpipe Hanger (99-01): https://www.rockauto.com/en/moreinfo....
-Probably some sandpaper -Probably also some exhaust paste for sealing up leaks -Exhaust hanger removal tool you'll only ever use this one time: https://www.amazon.com/Exhaust-Remova...

EXHAUSTS RANKED FROM WORST TO BEST
(In my personal experience and opinion)
-Stock (boring)
-Banks cat-back kit
-Flowmaster super 40 Delta flow (this video)
-Straight Piped with no catalysts or muffler
-Flowmaster Super 44
-With catalysts but no muffler (side exit) (epic)

I have no regerts with this new muffler, but the side exit thing was really starting to grow on me. Check out the secret video:    • Side Universe Exhaust [Bonus Video]
