What is the main benefit of a glasspack muffler?

What material is this MagnaFlow muffler made from?

This MagnaFlow Red Pack muffler is constructed from aluminized steel, which is chosen for its durability and resistance to corrosion, helping it last longer in various conditions.

Does this muffler come with any warranty?

About this part

Product Details

This MagnaFlow Red Pack glasspack muffler features a 3.5-inch round body with a 22-inch length and 2.25-inch inlet and outlet on each end. The aluminized steel construction is durable and resists corrosion, while the straight-through design allows for free flow and that classic glasspack sound. It’s a popular choice for adding a hot rod rumble to your exhaust system.

The reversible, straight-through design means you can install it in either direction, giving you flexibility when integrating it into your existing exhaust. While it’s designed for easy integration, professional installation is recommended to ensure it’s properly fitted and sealed. This muffler is dyno-proven for performance, offering a deeper tone and a bit more bark than stock.

Keep in mind that glasspack mufflers can be loud, so it’s a good idea to check local noise regulations before installation. This particular model comes with a 90-day limited construction warranty from Magnaflow.
