Holley is pleased to announce several new additions to their Flowtech brand of exhaust headers and exhaust systems. Read on to find out what's new. Flowtech has recently expanded its Axle-Back and Cat-Back exhaust applications with all-new kits for late-model Ford Mustang, Chevrolet Corvette, and Camaro applications. Like other Flowtech products, these new systems offer up the perfect combination of quality and value, all while producing an aggressive exhaust note under acceleration and a mellow tone at idle. These systems are constructed from 18-gauge stainless steel, feature 4'' polished tips, and have quality welds for strength, longevity, and great looks. Flowtech's new Long Tube headers and Off-Road X-pipe kit for 2009-2013 C6 Corvettes are a great way to add power and performance to your ride at an economical price point. The x-pipe is designed to work with the OEM muffler configurations. Both the headers and x-pipe are constructed of 304 stainless steel for a great look and maximum durability. Hardware, gaskets, and clamps are provided in the kit for ease of installation. Flowtech Long Tube headers and Off-Road Y-Pipe headers are a perfect combination for 2007-13 Chevy/GMC 4.8/5.3/6.0/6.2L V-8 trucks. They feature 3/8” steel flanges for durability and maximum sealing and long transition collectors with merge spears for maximum flow and increased exhaust velocity. Tube geometry is optimized for maximum ground clearance and ease of installation. They're 100% TIG-welded, with machined 3/8” header flanges and premium aluminum header gaskets and included attaching clamps for maximum seal and a fast, easy installation. This long tube header is available by itself or in a kit that includes the Y-Pipe. These systems are available in two finishes: black-painted or ceramic coated. Block Hugger mild steel headers for 331/354/392 Dodge Hemis have a tight-fit design ideal for cramped engine compartments and mandrel-bent tubes for consistent tubing diameters. Their smooth-transition primary tubes and optimized collectors deliver increased exhaust flow, instant throttle response, and sizable performance gains – even on stock engines. These block hugger headers come complete with hardware and gaskets for ease of installation. These headers are available in the following finishes: black, ceramic-coated, and polished. Special "shorty-style" mild steel headers with advanced geometry for ample clearance are now available for numerous applications, including 2011-14 Ford F-150s, 2007-2014 Toyota Tundras, 2005-2010 V6 Ford Mustangs, and 2011-14 5.0 Mustangs. They feature heavy-duty 16-gauge tubing for increased strength and durability. Mandrel bent tubing provides consistent tubing diameters for smooth flow and increased exhaust velocity. Please see below for available finishes specific to each application. Just for naturally aspirated 3.0L 1993-98 Mark IV Toyota Supras is a new 6-2-1 long-tube header design with mandrel-bent tubes for improved cylinder-scavenging and a smoother, more efficient flow. These polished stainless steel racing-style headers feature 1-1/2” primary tubes, 2” secondary tubes, and 2-1/2” collectors for maximum strength and exhaust flow. 16-gauge 304 stainless steel construction provides increased strength and long-lasting durability while a 3/8'' thick header flange aids in maintaining a leak-free seal and maximum strength.
