"All HKS exhaust systems are engineered for high-performance and durability. Each bolt-on system features high-quality mandrel bent, bake-coated aluminized steel piping and application specific muffler assemblies to maximize horsepower and torque gains."
Only the muffler is stainless, and yes the B&B is the highest quality exhaust, but I understand. I owned the $300 Pacesetter exhaust at one time.
