Long Tube Header for 1968-74 Oldsmobile Cutlass 5.7/6.6 - Ceramic Coated - 31150FLT FlowTech

Overview:

Flowtech headers are the perfect combination of performance and value. Flowtech long tube headers are precision engineered using mandrel bent tubing, formed collectors and 5/16" flanges with sealing rings for a leak-free seal. All mounting hardware and gaskets are included for a simple installation. This header is coated in a high heat and corrosion resistant metallic ceramic thermal coating that increases exhaust velocity and reduces underhood temps for increased performance.

Features:

• Fuel Economy From The Engine
• Leak Test For Max Performance
• Ceramic Headers
• Rust And Corrosion Resistance
• Mandrel-Formed Power Plenum
• Leakproof O-Ringed Port Seals
• Include All Mounting Hardware

Application:

Fitment Notes:

• Will not fit column mounted standard or floor mounted automatics or Cutlass Supreme models.
• Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage.
• The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.
• Recommended replacement gasket - Mr. Gasket part# 453
• Must modify exhaust system to retain catalytic converters.
