  • Which Dynomax to order

    I noticed some of you have #289-17739 which is 2.5" in and dual 2.25" out. Should I get this one or #289-17758 which is 2.5" in and 2.5" dual out. The diff in price is like $5. Is there a reason you guys went with 2.25" dual out?

    17758 is a muffler for a GM truck.

      17739 is also dual 2.5" out, not 2.25".

        Specifications from summit for #289-17739:
        * 2 1/2 in. offset inlet/dual 2 1/4 in. outlets
        * 19 in. x 4 1/4 in. x 9 3/4 in. case
        * 24 in. overall length

        If this is the muffler I need then what size inlet for the tips should I get. I want to get Z28 tips and they are 2.5"

          Summit has it listed wrong. I bought PN 17739 from Jegs.com, it's sitting in my room right now, and I can tell you it's 2.5" in/dual 2.5" out. NOT 2.25".

            get the dynomax ultra flo ss. I bought it for my car and it sounds bad a$$. It is a fully stainless steel muffler and is the highest flow series dynomax makes. It is not annoyingly loud inside, it sounds soo sweet, and from behind the car it is loud and mean sounding.

            DYNOMAX part #17266 $135.99 @ www.partsamerica.com/default.asp

            it is 2.5 in, and 2.5 dual outs. It is made specifically to bolt right up to our cars. (camaro/firebird)

              owh and by the way, the tips on z28 models thru roughly 97-98 are 2 1/4" inlet. (the rectangle shape tips), so you will need to reduce down from the 2 1/2 to 2 1/4, but thats cake, a reducer costs about $3 each, and about $9 each for a stainless one.
