New from Flowtech – they have expanded their line of late model axle-back and cat-back exhaust systems. These systems offer the perfect combination of quality and value for great performance gains. See more details below.

Official Release:

Holley/MSD is pleased to announce the release of Flowtech’s latest stainless axle-back and cat-back exhaust systems. Developed for three different applications – 6.2L 2010-13 Camaros, 5.0L 2013-14 Ford Mustang GTs, and 5.0L 2015-16 Ford Mustang GTs – the new axle-backs are made from three-inch 409 stainless steel for strength and durability. The perfect combination of quality and value offers both premium fitment and performance gains. All three versions feature high-flow chambered mufflers for a throaty sound without the drone and dual-wall exhaust tips with embossed Flowtech logos for extra style. Advanced tube geometry ensures a fast, easy installation using OE mounting points for factory-like fitment.

Stainless Flowtech cat-back exhaust systems are now available for 5.7L 2009-14 Dodge Challenger R/Ts and 2009-14 Ford F-150 trucks of all wheelbases and engine types. The Challenger system is 2.5 inches, and the F-150 system features a 3-inch into dual 2.5-inch design that’s compatible with all three popular engine types – 4.6L, 5.0L, and 5.4L. Both the Challenger and the F-150 systems are made of 409 stainless steel, come complete with high-flow chambered mufflers, and feature quality welds for strength, extra longevity, great looks and optimum tube geometry for ease of installation. The Challenger exhaust is specially designed to be a perfect fit for factory bumper-mounted exhaust tips.
