Holley is pleased to announce the release of Hooker BlackHeart Mustang Swap Long Tube Headers. Developed specifically for Coyote-powered 1996-2004 Ford Mustangs equipped with stock, Maximum Motorsports, AJE, or Team Motorsports engine K-members, they're a perfect fit for Blackheart engine swap brackets. They're manufactured from 18-gauge mandrel-bent 304 stainless steel and feature 1-3/4-inch primary tubes with long-transition 3-inch collectors for increased exhaust velocity and maximum flow. Ideal for NMRA Coyote Stock class drag racing, these long tube Headers are 100% hand-welded and provide factory-like fitment with stock clutch cables and steering shafts. When installed with Hooker Blackheart engine mounting brackets and transmission crossmembers, they're bolt-in compatible with several different transmissions – T45s, TKO 500/600s, T56 Magnums, MT82s, Powerglides, 4R70Ws, and 6R80s. They feature oxygen-sensor bungs in each collector, 3/8-inch flanges for extra strength and sealing, and advanced tube geometry for optimum clearance.
