        • Q:

          The OEM muffler has a tail extension that meets the resonator assembly and I do not see that in your view picture here. Is there a piece missing in the photo or do I have to add a piece of after market pipe to mate with the resonator assembly pipe? The stainless steel assembly has the extra pipe(s) but I do not need the SS package for my situation.

            A:

            I'm happy to help, JJs! This Flowmaster Inc. 40 Series Muffler (Part No. 43043) does not include the curved pipe in the exhaust to fit directly to the resonator assembly. This part may be purchased separately as Dynomax Part No. 52225 and if you also need the intermediate pipe to extend the front pipe, Dynomax Part No. 41801 is designed to connect the inlet of the muffler to the exhaust system. These are not available on AdvanceAutoParts.com, your local store may be able to source these parts for you. These parts are included in the Dynomax Super Turbo Kit (Part No. 19389) for your 2004 Dodge Durango 4.7L.

            A diagram of the exhaust is available from Walker here: http://mastercatalog.walkerexhaust.com/english/ExhaustCouponLargeScreen.asp?img=0896

            This Flowmaster Inc. 40 Series Muffler - 3.00 Offset In / 3.00 Offset Out - Aggressive Sound - part# 43043 takes the sound waves produced in the exhaust, and cancel them against angled baffles built into the muffler case. This improves both horsepower and fuel economy. Best of all, these Flowmaster mufflers allow you to hear that cool Flowmaster tone inside of the vehicle, as well as outside of it. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
