    Hardcore hot-rodders have known it for years-real power is really loud. And that's why hardcore hot-rodders use Magnaflow Glass Pack Mufflers. When maximum horsepower is more important than minimum sound, Magnaflow Glass Pack Mufflers deliver the hot-rod performance and classic roar you're looking for.

    Crafted from CNC-welded aluminized steel, Magnaflow Glass Packs feature a small diameter shell that fits into the tightest spaces. The straight-through performance design reduces backpressure, letting the horsepower flow freely. And to deliver that sweet hot-rod rumble, Magnaflow packs 'em with rockwool (non-fiberglass) acoustic packing material.

    Proudly made right here in the USA, Glass Pack Mufflers are crafted to the same high-quality standards that Magnaflow is famous for. And best yet, Magnaflow backs your Glass Pack Mufflers with a Lifetime Warranty.

    This muffler sounds fantastic on my 1999 Jeep Wrangler with the 4.0. Deep throaty sounds that you wouldn't expect from a 6 cylinder. It also sounds great on my brother's 1974 Chevy truck with a 350. I highly recommend it to anyone with a truck or jeep!

    Not real loud

    It offers a great low rumble when accelerating, but nothing to over the top. The more you drive the more you break it in.

    Deep agressive sound

    I had a plain old thrush muffler on the truck i bought which sounded good but wasnt loud enough. So i bought this which is quite a bit deeper and a lot louder and more agressive. Actually louder than i figured and wanted but i dont mind too much. But its a low deep rumble at low rpms and has a little glass pack crackle when you give it a little. I am very happy with it

    I bought these magna flow mufflers for my wife's '59 custom 300 because I saw chip foose advertise them a while back & I tried a dual chamber magna flow on my '12 silverado & it sounds good. I also have a '55 Cadillac that's going to have a set soon
