3" Downpipe Upgrade

The Classic Diesel Designs CDD 3" Downpipe Upgrade provides a 3-inch diameter solution for the IDI market, offering an alternative to the discontinued Banks 2.75" downpipe. This upgrade utilizes the factory marmon style flange and clamp for direct integration. This downpipe is specifically engineered to replace the factory crushed downpipes found on 7.3 IDI models. It can also be used to replace the slip joint downpipe and elbow on an ATS 093 kit, with the condition that a factory turbo style elbow is also installed. The product is available with or without a clamp, and with different coating options like silver or black, or no coating.
