Hedman Hedders 28140 Steel 1-5/8" to 2" Exhaust Header for Firebird/Grand Am/GTO PART NUMBER: 28140
BRAND: Hedman Hedders
DESCRIPTION Standard Uncoated HeddersPRODUCT DETAILS
- Standard Uncoated Hedders; 1-5/8-2 Tube Dia.; 3 Coll.; FULL LENGTH DesignHedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Pontiac models for decades. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Firebird, GTO, Lemans, Grand Prix or Tempest exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.The LONG-TUBE design provides ample exhaust flow to let your 326-455 Pontiac engine breathe easy, and produce maximum horsepower and torque. These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. They are also available with a ceramic-metallic finish.Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.Due to the location of the oil filter on these vehicles, relocation of the oil filter may be required to provide header tube clearance. We recommend the use of a Trans-Dapt Performance Products' #1120 (cast aluminum), or Hamburger's Performance Products #3365 (billet aluminum) oil filter relocation kit. Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
