Replace the Polyphonic Harmonizer behind the primary muffler in the ATAK? system with muffler 60679 to attain the "S-Type" sound level (quieter than ATAK?). Built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA? stands behind every direct fit muffler with a Million-Mile Warranty. Just what you?d expect from the world?s most experienced (and most winning) exhaust brand.
