Not a lot you can do the 4banger aside from swapping it out to gain much power. If you're looking for a good upgrade to keep those furious fighting squirrels still kicking like jackie chan than I would invest in an inertia ring. It's simply a 9lb weight attached to the flywheel to keep things spinnin'

Normally Banks exausts do sound good though, with the Chrysler 4cyl I had on my YJ my stock exaust sounded like a can of angry bees at high RPMs....vroom vroom....WWAAAAAHHHHH!!!

yea my old jeep sounded kinda lame, it had a coldair intake and a tb spacer. and a flowmaster muffler. im thinking of getting the banks torque tube and their cat back kit aswell. but i might also cut open my cat and chisel the inside out. my boss did that on his 8.1L chevy and it sounds even better than before. i just wonder if it will blow codes after that. theres some big computer thingy under my hood that i dont know what it does

If you go to an after market exhaust on that engine it gets really loud...and REALLY annoying. It sounds different than the 4.0 does. I tried two different after market mufflers, only to rip them both off and put the stock muffler back on.
