Delta Flow
Mild sound


For the person who wants a subtle custom appearance with all the benefits that a Flowmaster® Cat-back exhaust system provides. S.O.R. (Single out rear) systems are the perfect choice. As a Force II® system it produces a mild-moderate interior and exterior tone, and is suited to customers looking for efficiency improvements without too aggressive of a tone. The system is constructed from 2.50-inch mandrel-bent stainless steel flowing into a 60 Series™ performance muffler for a mild-moderate exhaust note. The mandrel-bent tailpipe uses the factory hanger locations, tucks up high in the chassis for good off-roading clearance and is finished off with a brushed stainless steel tip. Especially recommended for daily drivers or people who want a mild performance tone. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts, hardware and our Lifetime Limited Warranty. Note: Does Not fit extended wheelbase Unlimited model.
