    Classic Chambered PowerSticks beat any glasspacks in the sound department IMO and have no fiberglass in them, just louvers and the outer shell is "pinched" in 4-5 spots to create chambers. I've had them on my Duster since 2010 and wouldn't change them for anything. Loud and rowdy on the outside of the car but minimal drone on the inside and no popping/afterfiring to speak of.

    I really like Dynomax mufflers. I run them on pretty much everything, straight through design is my preference.

    I run this setup and its surprisingly quiet for what it is but lightweight and good flowing.

    Dynomax Performance 24250 Dynomax Mini Race Bullet Mufflers | Summit Racing
    Summit Racing SUM-681300 Summit Racing™ Lap Joint Band Clamps | Summit Racing
    The bullets just slip fit so no welding and you can take them off pretty easy and just run the collector extensions. The extensions fit well with the "exit" of the headers in relation to the cross member as well.

    Yeah, I'm about 40 years too old for header mufflers on the street for my cars, but that's what the op was asking for.
    Then again, I have straight thru magnaflows off the fenderwell headers on one of mine, right now. They are the longest ones I could fit, however.

    My advice, buy the cheapest glasspacks you can find; because you’ll be throwing them in the dumpster before too long.

    Dougs or hedman/hooker/flowtech generic ones, easy to clock and tuck up tight, of course tti's have the angle exit and don't play nice with them.

    Yea I thought so. I use them on the standard 1-5/8 headers. They clear the trans crossmember great. There a huge help of you want to install an H pipe.

      Hey there,
      I just got mine out and blew the dust off. These days it's the only way I can afford gas to go to work

        I love the sound of glass packs, especially before they get blown out. I go with the longest ones I can find and put them as far back as I can, in front of the rear end.

          Been running straight pipes since the 70's and have never had ticket....but, I also run a full system all the way to the bumper and that helps. Did have a 66 Mustang Fastback with a mild 289 with Smithy's Green Power glass packs that exited out in front of the rear tires. All those things did was amplify the noise lol. You can also tone down a straight pipe system by using a larger diameter pipe and add a lot of crimps to it. Doesn't hurt the flow either....boundary layer air is slow anyways and the center layer is what moves and the crimps help to reduce the sound waves. I've found some mufflers shops had crimping dies but don't know of any around here anymore. Most of the mom and pop exhaust shops have closed down. If you use 1/4" deep crimps, add 1/2" diameter to the pipe you use to crimp. The last one I did only had 1/8" deep crimps and were done with a muffler clamp (pita) in a 36" long pipe but only did 7 crimps. Made a difference but not all that much. One of these days I'll make my own crimping dies.
