Flowmaster 10 Series Delta Flow Muffler

The Flowmaster Super 10 Series Delta Flow Muffler (FLM-8425154) offers one of the most aggressive exhaust tones in the Flowmaster lineup. Constructed from durable stainless steel, this muffler utilizes patented Delta Flow technology, similar to that found in the Super 40 and Super 44 series, to maximize performance. Ideal for racing applications, the Super 10 Series muffler is not recommended for most street-driven vehicles due to its extremely loud and aggressive sound profile, delivering an exhaust note that is as close to an open pipe as possible. Its compact, single-chamber design contributes to its intense sound and allows for easier installation in various configurations. Installation involves working with new or existing exhaust systems, offering slip-on capability that can be welded or clamped into place. For clamp installations, Flowmaster recommends spot welding the joints due to the heavier materials used. Some applications may require cutting or splicing into the existing exhaust system for proper fitment. This muffler is backed by Flowmaster's limited lifetime warranty for stainless steel mufflers, covering defects in materials and workmanship when installed on the original vehicle. However, the warranty explicitly excludes products installed on racing vehicles, installed improperly, altered, misused, or damaged by accident, collision, or road debris. Normal wear, including sound level degradation and cosmetic issues, is also not covered.
