Description
Even More Performance Than the 40 Series. Flowmaster’s 40 Series is already a performance legend but the 40 Series Delta Muffler takes this to a new level, with Delta reflector internal design for even greater scavenging and, hence, more performance. Made from superior-grade materials using the finest manufacturing techniques, this superb muffler gives you a nice aggressive tone to match its competition-level performance.
Aggressive Tone, Reduced Interior Resonance. Rock out that performance exhaust sound with the 40 Series Delta muffler. You’ll get real meaty aggressive sound to go with the enhanced performance that will stand out, whether you’re rolling on the street or hooking it up at the track. Interior resonance is further reduced compared to the regular 40 Series.
409S Stainless Steel, No Internal Packing. Flowmaster produces the 40 Series Delta using its own patented technology to provide optimized gas flow tuning without any internal packing to blow out. The muffler is built of superior-grade 409S stainless steel in hefty 16 gauge, fully MIG-welded for robust integrity. The rugged black coating stands up to thermal stresses and wear.
Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.
Application. The Flowmaster 40 Series Delta will work with your 1999-2024 Silverado 1500.
