Holley/MSD has released a new product: Hooker BlackHeart 2015-17 Shelby Mustang Long Tube Headers. Compatible with both GT350 and GT350R models, they’re engineered to fit factory exhaust systems with BlackHeart link pipes and are fully compatible with four complete exhaust systems (part numbers 70503350-RHKR, 70503351-RHKR, 70503352-RHKR, or 70503353-RHKR).
BlackHeart 2015-17 Shelby Mustang Long Tube Headers are made from mandrel-bent 18-gauge, 304 stainless steel for maximum strength and durability and feature 1-3/4-inch-diameter tuned-length primary tubes and long-transition 3-inch collectors with merge spears for optimized flow and increased exhaust velocity. Every piece is 100% hand-welded, tube geometry is designed for maximum clearance, and factory-like mounts accept OE vibration dampeners. They come complete with O2 sensor extension wires and all the necessary hardware for a fast, easy installation.
