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.
