            Great fit, sounds good!

            I'll start off by saying I mated this to an aftermarket long tube header on my I-6. That being said, every exhaust part was new. So, the header, this crossover and cat, and MBRP cat back and my inline 6 cylinder sounds MEAN! The install was super easy, again because the old exhaust was saws-all'ed off (LOL) and it passed e-check no problem.

            Great Catalytic Convertor

            This this is amazing with a straight pipe after the cat. It gives your jeep the sound that its balls dropped. At low rpms it sounds like a truck and at higher rpms it sounds more like a sports car. The other bolts people are talking about do help but i managed to get mine on with the stock bolts. LOVE THIS THING!!!!!!

            Super easy install. No more check engine light when I hit the interstate. Could not be happier. I replaced from the exhaust manifold back, I also replaced the O2 senors while I was down there. I highly recommend this product

            Good

            Me myself I was very pleased with the product and I'm very pleased with it sounds good it's getting good flow and airflow the only thing I have to say is is it is not a direct fit my 99 Jeep Wrangler manual 4.0 I had to drill out the holes for the downpipe for the flange which really was no big deal but just so you know you do have to drill out those holes at least on a 99 Jeep

            Wonderful product

            Was a bit challenging getting the old pipe off being 19 years of rust getting in the way but it was an easy install. Already seeing an increase in fuel economy after 2 tanks and the exhaust note got a little raspier. Really pleased with how it turned out

            Nice little improvement in performance (no other changes being made). Great fit and hundreds ($) less than OEM if I could have found that.

            To Easy

            Purchased for my 98 Jeep wrangler muffler guy had cut out my catalytic which affected my service light. All i had to do is cut away the trash work that was done and buy a slide on sleeve for joining at the rear. First rate product easy off and easy on, a few clamps and your done. Fits like factory. The hardest part was taking the saw saw to get the old stuff.
