    Nice, Cobra came out with a more reasonably priced set for the Freewheeler in there line up of mufflers offered.

    Cobra has some nice slip on freewheelers mufflers and they are very nice indeed. I looked at a pair of them real hard, they also sound very nice.. I went with the D&D 3 1/2" Touring mufflers with the 2" diameter vortex baffles instead and I like them a lot.

    The only reason I chose the D&D mufflers over the Cobra mufflers was the baffles in the Cobra slip ons where 2 1/2" in diameter. I have found more often than not over the years when you go to a bigger baffle than a 2" diameter in the mufflers on a stock Harley motor you tend to loose a little bit of low end torque. I just did not want to take the chance that the Cobra mufflers larger baffles would affect the trikes low end torque.

    Manufactures today because of the catalytic converters are going to bigger baffles to get the sound out of the mufflers. I think for the most part this is because of the muffling affect of the catalytic converters. It's a well known fact when the cat is removed the exaust system gets louder.

    Ride Safe,

    Bill G

    That baffle looks to be a 2" baffles. I could be wrong as the pic could be a little deceptive to the eye because of the angle in the pic. The baffle looks a lot like or similar to the 2" Vortex baffles I have in my D&D Exhaust 3 1/2" touring mufflers. It does not look to be a 2 1/2" baffle like the baffles in the more expensive Cobra mufflers that you looked at with the black ends on them. If this is the case these mufflers should maintain or not cause a loss of any of your lower end torque . I bet they will sound nice too, deep and not overly ear breaking loud. With the cat still in more mellow, louder without the cat for sure if you decide to remove it. I left my cat in and find my sound to be just fine also the performance is good with no hiccup's.

    Those really look like sweet mufflers. Let us know how the install goes also what you think of the sound and performance.

    Ride Safe,

    Got the mufflers on. Not to bad a job. You do need to turn the mount around to help put the bolts in. You should all so get some longer bolts. The ones that are in are 1/2 you need 3/4. The reason is the bracket does not set just right on the muffler mounts. They really sound great. I went for about a 135 mile trip. Not loud just the right sound for me.

    Bill,
    can you provide the D&D part numbers for they have two different 3 1/2 Vortex slipons, and what end caps? They look good with the bumper and not hideously ticking out like most.

    Default Sound

    I have a 2019 Harley Davidson Freewheeler. I am looking for loud mufflers. I currently have CFR baggers and they have a good sound, but not loud enough for me. Are the Cobra 909 twin 6302 louder?

    909s have a beautiful deep rumble. The perfect balance between to much and to low.

    I can’t recommend them enough.

    Here's another option...Low cost and produces the best power of all the slip-on's we've tested (except for the SuperTrapps which are relatively quiet).
