Flowmaster introduces our FlowFX Extreme stainless steel cat-back exhaust systems for the 2014-2019 and 2019*- 2021 (*new body) Chevrolet/GMC Silverado/Sierra 1500 trucks with the 4.3 and 5.3-liter engines. These systems use a FlowFX series muffler for an aggressive to moderate sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The systems have a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. Max dyno gains of 15 hp and 20 lb-ft at the rear wheels with the 717977 kit. All of the necessary hardware is included, and factory- mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.

Flowmaster operates the only exhaust Research & Design facilities of its kind in the world, centered around the SuperFlow SF-7100 engine dynamometer complete with E.C.A. (engine cycle analysis) equipment and also SuperFlow chassis dyno's. Through use of these dyno's, Flowmasters engineering staff can track the complete engine cycle in millionths of a second and can obtain exact technical data of each degree of cam rotation, from induction to the tip of the exhaust system, while also showing the power numbers that really matter, the power numbers to the ground. Flowmaster also utilizes Spectrum Analyzers to fine tune the sound of each of the eleven different series of mufflers that Flowmaster currently offers, both for peak performance and just the right sound levels and tones. Flowmasters product line includes exhaust products for Performance Street, Muscle cars, Trucks, Street Rods, RV's, Motorhomes, and all types of race applications. With over 400 different muffler models, 370+ exhaust systems and numerous exhaust accessories available, Flowmaster offers you the choice of sound to fit your sound preference from wild to mild and of your specific vehicle needs. Call our experienced tech staff for live help and detailed information regarding your vehicles. With Ray still active and hands on with the R&D department in the development, not only of new exhaust products, but also with new technologies currently being tested in third and new R&D facility, the future looks to be very exciting indeed.
