    Ground up rebuilding
    I'm building a 1994 Jeep YJ from the ground up and I have replaced or rebuilt most everything and I'm wanting to put headers, or well a header on this lil 2.5 Ltr. I see a few brands out there and the reviews are mixed. I'm ordering a stock replacement exhaust system from the "manifold to tail pipe" and want a good header to bolt up. I have a 4.5" RR lift. Any help would be appreciated as I'm a first time Jeep owner. Thanks.

    I don't know about a 4cyl, but long tube headers create more torque at lower rpms. Therefore if you went with a long tube header a stock exhaust system won't bolt up. You will have to modify it some.
