If you've ever been disappointed by the horsepower figures coming from your Jeep Wrangler JK, whether it has the 3.8-liter or the 3.6-liter V-6, and you've considered an LS swap, you're not alone.

I'm planning to retrofit a late-model LS engine into my 2002 Jeep 4x4, and want to fabricate my own exhaust headers. It needs to conform to California emissions standards. I don't want ugly "smog" ...

I am looking to upgrade my 2002 Jeep Wrangler TJ with a HEMI V-8 for some much needed power. So far I have not found a company that makes a kit that seems to have everything and has a good reputation.
