Gibson Exhaust Systems for 2007 and up Chevy Avalanches.

All Gibson Exhaust Systems come in Aluminized Steel or Stainless Steel. Price shown is for Aluminized Steel. Both choices are very high quality but Stainless is $155.00 more than Aluminized Steel.

System Choices:


  • Dual Sport  - Dual pipes exit behind the rear tire.
  • Dual Extreme - Dual pipes exits behind the tire on each side at a very aggressive angle.
  • Spilt Rear (Shown in thumbnail picture)  - Exits straight out the back.
  • Swept Side - Exits behind the rear tire.

    Aluminized Steel Construction: Aluminized steel is steel that has been hot-dip coated with an aluminum-silicon alloy to protect from corrosion. Aluminized steel has the satiny surface look and feel of aluminum, with the strength and lower cost of steel. This makes it a great choice for fabricating an exhaust stytem that is strong, durable and cost-effective.

    Stainless Steel Construction: Stainless steel is essentially a low carbon steel which contains a certain amount of chromium, giving it the ability to resist corrosion. The addition of chromium is also the reason that Stainless Steel is so easily polished. Because it is just as strong as regular steel, and is able to resist rust, stainless is a popular material used in the construction of exhaust systems.
