$155-$175MagnaFlow 14216 5x8x14" Oval Straight-Through Muffler
The 14216's 5x8-inch oval body tucks cleanly under low-clearance vehicles where a round muffler won't fit — making it the go-to choice for muscle car restorations and performance street builds. Center-in, center-out 2.5-inch configuration in polished stainless steel with the same straight-through perforated core and lifetime warranty as MagnaFlow's round lineup. Manufactured in Oceanside, CA.
$140-$165MagnaFlow 12866 5x5x14" Round Straight-Through Muffler
The 12866 steps up to a 5x5-inch round body — 25% more cross-section than the 10416 — for higher-displacement engines that need additional exhaust volume without sacrificing the compact 14-inch body length. Straight-through perforated stainless core with stainless mesh and acoustic fiber fill, 2.5-inch center inlet/outlet, and full stainless construction with a satin finish. Made in Oceanside, CA.
$100-$120MagnaFlow 10416 4x4x14" Round Straight-Through Muffler
MagnaFlow's best-selling compact performance muffler — a 4x4x14-inch round body in satin-finish stainless steel with a straight-through perforated core wrapped in stainless mesh and acoustic fiber fill for free-flowing exhaust and a deep, resonant tone. The reversible 2.5-inch center inlet/outlet fits most domestic and import cars and trucks. CNC precision robotic construction with a limited lifetime warranty.
