SKU: IAW00312 Category:

Optional Cerakote can be applied to both the 4.5" and 5" downpipes:

Cerakote reduces heat transfer from the downpipe to the surrounding components, helping to keep the engine bay cooler and protect nearby parts like coolant hoses, wires, and other heat-sensitive materials. Cerakote also enhances heat dissipation which reduces the temperature of the exhaust and turbo, improving overall performance (more power) and potentially extending the lifespan of the turbo.

Fitment:

Fits all G Chassis B58 Engines! Fits both RWD/AWD (X-Drive) models
