Borla header and exhaust install.

    I am about to install a new header, cat, and muffler on my 6cyl TJ. I was just wondering if you guys could give me some heads up as to what I might run into. I am not used to working in engine compartments that are so small that you can barley turn a wrench in. I also am going to install a Powerdyne Power plate throttle body spacer. Powerdyne claims it will give a 6cyl TJ a 20 hp increase. Hopefully with both of these combined I will have a little more import slaying power.

    You will have to take most of the crap off the exhaust side of the engine to get to the exhaust/intake manifold bolts. On a CJ, the exhaust and intake manifolds share the same bolts. I imagine the TJ is the same. It's a pain. Only install the exhaust finger tight until it is all assembled. Then start tightening everything down starting with the header and working your way back.


    Don't do it on a day when you only have a few hours. It can become a weekend project very fast.

    I was able to get it done in about 3 hours. It was a huge pain and I hope I never have to do it again. With the new cat and muffler the Jeep sounds awsome, as close to a v8 as you can get.
