Looking for help with my newly acquired 03 500 4x4 auto. I'm look to wake this thing up a bit. I mostly ride trails, and mudd so a snorkel kit is definitely a must, but I want more power and torque. Where do I start?

Some north eastern states in the US its illegal to have a modified muffler. The game police will check you with a sound meter. Also, snorkels are illegal as well.

Maine for example...

Personally I would get them machined.

Machined how? Who do I see to have this done? I assume it's like swapping out to a lighter flywheel in a car? It has less rotational mass so it frees up horespower?

But I will warn you, if you choose to mail him your clutches, be prepared to wait about a month for them to return.

You can also add a shim and lighten your rollers.
