The Types of Glasspack Mufflers

First of all, it’s important to know how glasspack mufflers are different from the rest. Most mufflers that come standard with your Flowmaster exhaust system or Borla exhaust system are conventional performance mufflers that reduce the sound level a bit. And, because of all the turns and holes that the exhaust must travel through, these mufflers may produce a fairly high back pressure, which does subtract a little from the power of the engine.

Glass pack mufflers, on the other hand, use only absorption to reduce the sound. So, the exhaust goes straight through a pipe that is perforated with holes. A layer of glass insulation surrounds this pipe and absorbs some of the pressure pulses. A steel housing surrounds the insulation. Therefore, glass mufflers, like the Magnaflow Glass Pack Mufflers, produce much less restriction, but don’t reduce the sound level as much as conventional mufflers.

Mike Cote
My 2015 Toyota Tacoma TRD Off Road Access Cab 4x4 offers bed space to camp in, haul my dirt bike around, and it's been done up to take on the trails. Favorite mods include my Icon coilovers to soak up the bumps. My Walker Evans 501 Legend wheels wrapped in Toyo RT tires give me the clearance from my upper control arms to fit (and they look darn good) and the over-sized tires take on rocks with plenty of traction. My Rigid Industries fog lights have kept me out of a ditch or two when night wheeling. Growing up going to car shows and helping my dad work on the family vehicles ignited my passion. My best memory was the first time I flushed the coolant. My dad forgot to tell me to keep my face out from under the drain plug. Never made that mistake again!
