    Flowtech Exhaust 12147FLT Details

    Flowtech Headers are the perfect blend of quality, performance, and value. These 1-3/4" shorty style performance headers fit the very popular 5.0L V8 for the Fox-Body Mustang platform. The 1-3/4" tube size is the perfect upgrade for stroker motors and engines that have limited clearance issues and still require a free flowing header.
    • Mandrel-bent 409 Stainless Steel tubes provide consistent tubing diameters for smooth flow and increased exhaust velocity
    • Heavy duty 16-gauge tubing for increased strength and durability
    • Smooth transition, 1-3/4” diameter primary tubes are used for increased exhaust flow increasing performance and improving throttle response
    • OE style 2-1/2” ball and socket collector connects to factory exhaust head pipe with no cutting or welding
    • TIG-welded, machined 3/8” header flange for a leak-free seal and maximum strength
    • Premium aluminum header gaskets included
    • Available finishes include: High Temp Black Painted, Ceramic Coated and Polished
    • These headers are a must upgrade if you are using a cold air intake, cat-back exhaust system or performance cylinder heads
