Material selection for daily‑use aftermarket exhaust systems
Daily‑driven exhausts face rain, road salt, temperature swings and constant vibration, so material choice directly controls service life. Fupower daily exhaust lines mainly use 304 stainless steel for excellent rust and corrosion resistance. It balances cost, durability and appearance for street vehicles. 316 stainless steel is available as an upgrade for coastal markets with heavy saltwater exposure. Titanium exhaust is lighter and handles high heat well, but higher cost makes it more suitable for premium builds rather than standard daily commuter cars. Budget mild steel exhausts cost less but rust rapidly and need frequent replacement, which leads to more customer complaints. Fupower’s QC includes weld inspection and pressure leak testing for every exhaust assembly before shipment, reducing field failure risk for wholesale customers.
