The COBRA El Diablo 4" Slip-On represents a fresh design evolution inspired by the earlier El Diablo 2-into-1 model. At its core, a spun-louvered internal structure is engineered to deliver the characteristic sound signature and horsepower gains associated with the brand. The muffler body itself is manufactured in-house rather than outsourced, beginning as a 2.75-inch tube that expands into a 4-inch cone megaphone shape at the rear.
Finishing touches include a machined beveled tip that aligns with the megaphone’s contours, along with an etched Cobra logo on the top surface. This exhaust system is available in two distinct finishes: Chrome with a Black tip, and an all-Black configuration with a Black tip.
