MBRP Armor Lite 4" HX40 Turbo Style Downpipe 98.5-02 Dodge 5.9L Cummins

The majority of aftermarket upgraded turbos for your 2nd Generation Cummins (98.5-02) feature a different exhaust discharge compared to the restrictive factory unit. This requires the use of what most called an HX40 downpipe that eliminates the stock cast elbow found on the stock HX35 or HY35 series turbos. This piece from MBRP is designed to mount up to turbos featuring this HX40 discharge in conjunction with an existing 4" exhaust system.
