SPD HX Series Axle-Back Exhaust is the ultimate performance exhaust system for those that enjoy a mild, deep and drone free exhaust. Manufactured using 304 stainless steel mandrel bent 3" tubing and HX Series muffler, our axle-back systems are designed for maximum performance and longevity.

HX Series mufflers use a hard packing sound dampening material that doesn't break down from the harsh harmonic vibration and heat cycles. Other manufacturers use loose fiber/mesh materials that breaks down, which is why they get louder and have more drone each year.

Installation is a breeze with our systems being 100% bolt on with no cutting needed.
