    Hi folks,

    Have spent hours looking for those very small (12"-14"?) "mini-mufflers" (probably not the correct term) that can be attached somewhere in the tailpipe in order to quiet down the exhaust note a bit. I believe they are straight-through and, thus, do not affect flow. Any help would be appreciated. If they are not the 2" I am specifically looking for, the inlet/outlet size can be adjusted, of course.

    Thanks!

    They are called resonators. The big cars had them I believe. Maybe something like this?

    Don't know what part numbers you're looking for, but what you're looking for is called a resonator. Try searching that term. :TU:

    Thanks, guys! Of course, I replaced many of them in the old days, and Larry is right--the big cars usually had them.

    Then, to save money, if the customer didn't mind a slight extra noise, the exhaust companies starting selling resonator-eliminator pipes--a complete tailpipe with no provision for a resonator.

    Didn't think what I was looking for was still called a resonator but I guess I was wrong!

    Thanks, again!

    This is an interesting question for the race section of the forum.
    I thought when I came across this it would be something related to the 2" pipes for each cylinder so commonly seen :)

    Also try searching bullet mufflers. I have 2.5" Dyno Max bullets in my tailpipes.

    Yes, wanted to put some 2.5" bulllets in my tailpipes to quite down the 3" exhaust with the long-case Walkers.

    [​IMG] Here is a pic of the bullet muffler that Rob is referring to . Norm used to say it takes the "bark" out of the exhaust .

    Wow, they fit better than I thought, and very discreet! Yes, just want something to "take the bark out of the exhaust."

    Thanks, again!

    12lives Control the controllable, let the rest go

    I believe that's a Walker 24215 bullet mufflers:
    In/Out: 2.5''
    Overall Length: 16.5''
    Shell Length: 12''
    Diameter: 4''
    Aluminized Steel

    comes in SS as well.

    Thanks! Stainless is always nice but, and correct me if I'm wrong, harder to weld. Welding makes a cleaner installation in this instance, compared to clamps.

    Thanks, again!

    I'm not a welder but my whole system is custom and 100% stainless. It's been on the car for 16 years and still looks like the day it was built. I just match the muffler material with the pipe material.
