Stainless Round Muffler, Polished finish, Resonator Style (2.5" and 3")

Glasspack mufflers feature a straight-through design with perforated cores wrapped in sound-absorbing material, allowing for less backpressure and a louder, more aggressive exhaust sound compared to traditional chambered mufflers. They are much smaller and much louder than traditional mufflers.

Yes, many people who want to "straight pipe" their exhaust but still need to pass their state visual inspection for a muffler will install these. They are as close to a straight pipe as you are going to get!

Some users report increased interior drone with glasspack mufflers, especially at certain RPMs. Adding a resonator or choosing a longer glasspack can help mitigate this issue.

These smaller mufflers are the most aggressive option we make. They will be loud and they will be a higher pitch than our oval mufflers. They are comparable to Carven and many other 4" body mufflers like Flowmaster, Magnaflow, and Total Flow.
