    My cure was to just get rid of them, I went with Headers and so far no more cracks, exhaust leaks etc. Almost forgot how my Jeep was supposed to sound because it's been so long that lve been dealing with this problem.

    What kind of headers did you go with? I've heard some horror stories with some

    Jeep briefly had a lifetime powertrain warranty for vehicles sold in 07 (some 06 models were covered depending on sell date) and extended though the 08 model year. I had an 07 Liberty that had transmission issues that the dealership couldn't seem to get completely fixed. I got tired of dealing with it so I traded it away.

    09's had the lifetime powertrain as well. Mine has this and they have replaced my driver side exhaust manifold under warranty. ( rear main seal and rear wheel bearing). You have to go in every few years to keep the power train warranty in effect. If you lapse, they will cancel it. With 37's, 3.5" lift, and supercharger I'm not sure how I still have it.

    I have a 12 with the lifetime warranty but I also paid extra for it. Probably not the best investment. Exhaust components are covered under a federal 8 year 80k warranty regardless of make or model. If you're in that window I'd start there. If you have the lifetime power train warranty I'd assume this would be covered as well. To clarify depending on the headers they are not SMOG exempt. Here in CA I have JBA's on my Titan. Depending on the vehicle they are CARB compliant. The same CATS I had installed are compliant on my truck but not on the Armada (Same exact motor). They'll pass the obd 2 test but will fail the visual as its "modified". Hope this helps

    California smog emission standards blow. I couldnt just by oem exhaust maninifolds. I had to buy CA compliant exhaust maunfolds that cost more. And forget the notion of .CA compliant headers unless your willing to blow over $1k for them.

    I also installed the JBA plug wires and have not had any issues with them melting.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
