{"product_id":"3800-v6-stainless-steel-exhaust-header","title":"3800 V6 Stainless Steel Exhaust Header","description":"The Flashark exhaust header is a high-performance racing component constructed from T304 stainless steel with a mirror polish finish. It features a TIG-welded CNC machine flange and a 6-2-1 design, which is optimized for the firing order of the GM 3800 V6 engine. This design enhances exhaust scavenging, where high-velocity pulses from one cylinder help pull exhaust from the next, leading to improved volumetric efficiency and increased power across the entire RPM band.\n\nThe kit includes the front and rear headers, crossover pipe, and necessary metal gaskets and mounting bolts. For optimal performance and engine safety, a PCM recalibration is highly recommended after installation to manage air-fuel ratios and prevent knock retard. The included O2 sensor bungs accommodate factory sensors, but a Check Engine Light may occur and can typically be addressed through custom tuning or O2 sensor spacers.\n\nThis header is specifically engineered for models factory-equipped with 3.8L V6 Supercharged (L67) engines. It is verified to fit the Pontiac Grand Prix (1997-2003) and Buick Regal (1997-2004) with the 3.8L L67 Supercharged SOHC V6 engine. While it shares the same head bolt pattern as the naturally aspirated L36 engine, custom exhaust work may be required for a perfect fit on L36 applications due to differences in crossover pipe and downpipe routing. For 1997-2003 Pontiac Grand Prix GTP models, installation is generally direct-bolt-on, though minor adjustments to the crossover pipe or clamps may be necessary depending on the specific year and engine mount condition. The manufacturer recommends using heat sleeves for spark plug wires or upgrading to angled boots to prevent heat damage, especially on the rear bank, due to the increased heat radiated by the headers.","brand":"Flashark","offers":[{"title":"Default Title","offer_id":52688301752632,"sku":"FLES08036","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663173750.webp?v=1784889138","url":"https:\/\/store.motormia.co\/products\/3800-v6-stainless-steel-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
