GMC Envoy Performance Exhaust Systems

You rely on your Envoy for so many tasks. Some of which are taken for granted until a nasty exhaust problem puts the “brakes” on your daily chores. Even a quick drive to the store can become unbearable with the perturbing sound of obnoxious exhaust blasting out from your premium SUV! The exhaust is made up of a series of parts that start right at the engine with an exhaust header, which then attatches to a converter, resonator, 2.5” OD piping and other sound muffling devices. All these parts have the potential to fail.

The dealer might seem the best choice for replacement parts – to the uninformed Envoy owners of the world, that is! You know better though, and trust us to bring you the best value on any part you need for your vehicle. Bosal is just plain awesome! They make the very best exhaust components, while their prices make the dealer's look obscene. A Bosal 113.0” Catalytic Converter for a 2002 model Envoy is a steal for under three-hundred-bucks. It literally has no distinctive differences from the official GM part, other than the low price. All the stock hangers are in place, the dimensions are the same, and it's perfectly legal in every state and province other than California (residents should always look for the “CARB” designation on all exhaust system components.) This is just one great example, see inside for parts to fit your specific Envoy.
