{"product_id":"lt-swap-longtube-headers","title":"LT Swap Longtube Headers","description":"These headers are designed with precise mandrel bent tubing, featuring 1 7\/8\" primaries that transition into a 3\" collector, complete with merge spikes for optimal exhaust flow. The CNC machined flanges ensure a secure and leak-free seal.\n\nDesigned specifically for V8 LS engines during an LT swap, these headers are compatible with 5.3L, 6.2L, LT1, and LT4 engines. The natural stainless steel construction and tig welding underscore the quality build intended to balance performance and affordability.\n\nInstallation may require fabrication due to older vehicle frame clearance, as the headers are pulled in very tight and will necessitate the use of specific spark plug wires. If utilizing a larger 4L80E or older Turbo 350\/400 transmission, trimming of the bellhousing ears might be necessary for adequate clearance. Additionally, adjustable motor mounts with a 1\" offset back may be required. It is important to note that these headers are intended for race-only applications and may not be legal for use on public roads.","brand":"Speed Engineering","offers":[{"title":"Default Title","offer_id":52663771726136,"sku":"25-1165","price":369.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687686720.jpg?v=1784329462","url":"https:\/\/store.motormia.co\/products\/lt-swap-longtube-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
