    i have a header on my 4.0 idk what brand it was put in about 7 years ago will this bolt up to it or does it only work with a stock manifold?

    Chance

    • The MagnaFlow Direct-Fit Catalytic Converter is designed to be a bolt on to the factory exhaust pieces. They have not been tested with aftermarket pieces, and will most likely require custom modification that we cannot advise on.

    Does this require any welding? If not does it come with clamps?

    JoshB

    • The Magnaflow Direct-Fit Catalytic Converter will not require welding and would use clamps for the install.

      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

      Great system

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

      Easy Install, Great Product

      This catalytic converter went on easily, sounds great, it looks great, and is a decently fair price. I have always liked magnaflow exhaust systems, they never disappoint.

      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.

      Very satisfied.

      Although i had to buy the muffler and tailpipe afterwards because the existing exhaust was larger diameter than the catalytic portion of the exhaust system. My wife likes the quieter drive so rated two stars for loudness volume. Rated exhaust note a 3 as it is in the middle range meaning just about perfect...Jeep had a surge under power with old exhaust but much better now so think this has better back pressure for the engine.

      Great Replacement Catalytic Converter.

      I needed a replacement catalytic convert for my 98 Jeep wrangler. The MagnaFlow direct fit catalytic converter has the best price for an all stainless steel replacement. It arrived with everything need to replace the factory converter and pipe. After cutting the old assembly out at the muffler the new one was installed in less than an hour. Installation was easy. I only needed one adapter to go from the converter outlet to the muffler. I would recommend this product to anyone that needs to replace their catalytic converter.
