40 Series Delta Flow Chambered Muffler
This two-chamber design incorporates Flowmaster’s patented Delta Flow® technology. The Delta deflectors generate increased scavenging for better performance and reduced interior sound. You’ll enjoy a milder exterior tone and significantly less cabin resonance compared to the standard 40 series. Built to last, it’s constructed of 16 gauge 409S stainless steel and fully MIG-welded for maximum durability.
- No internal packing to blow out
- Excellent for street/strip and off-road applications
- Race-proven, patented Delta Flow® technology
- Durable, fully welded 409S stainless steel construction
