MagnaFlow 12279 5x8" Oval Straight-Through Performance Muffler (3" In/Out, 24" Body)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
The MagnaFlow 12279 performance muffler is engineered to deliver a smooth, deep exhaust tone while improving flow through a straight-through perforated stainless steel core. This universal-fit muffler features a bi-directional design, allowing for flexible installation in either orientation to suit your custom exhaust plumbing.
Constructed from 100% durable stainless steel, the 24-inch oval body is produced using CNC precision robotic manufacturing for long-term reliability and corrosion resistance. The internal core is wrapped in stainless steel mesh and acoustic fiber fill to manage sound without restricting exhaust velocity. This muffler is ideal for custom builds requiring a 3-inch center-to-center configuration.
