The Walker 54454 is an aluminized steel front exhaust pipe for the 2000–2002 Nissan Sentra. It is a direct-fit replacement for the original pipe, so it bolts up to the factory mounting points without fabrication. Aluminized steel resists corrosion better than plain mild steel, though it is not stainless. It suits Sentra owners replacing a rusted or cracked front pipe who want a stock-style fit rather than a custom or performance exhaust.
