Description
Overview
The Flowmaster 50 Series Delta Flow Chambered Muffler brings proven Flowmaster performance and a moderate, refined exhaust tone to classic muscle cars and beyond. Built around a three-chamber design, it pairs Flowmaster’s Delta Flow® technology with an internal tuning chamber to knock down interior resonance while preserving the aggressive exterior tone enthusiasts expect. The result is a muffler engineered to deliver the same performance and exterior sound characteristics as the two-chamber version, but with a smoother, quieter experience inside the cabin.
Delta Flow Technology & Sound Control
At the heart of this 50 Series muffler is a purpose-built acoustic strategy. The three-chamber layout channels exhaust through Flowmaster’s Delta Flow® internals, while a dedicated tuning chamber targets and reduces sound inside the vehicle. That means you can run a serious exhaust setup without the constant drone on the highway or during long cruises — a moderate sound level that stays assertive outside while remaining livable inside.
Built to Last
Durability is designed in from the start. The muffler body is constructed from 16 gauge aluminized steel and fully MIG welded for maximum strength and long service life. A high-temperature paint finish helps the muffler stand up to the heat and demands of a real exhaust environment, making it a dependable choice for street-driven classics and daily performance builds alike.
Fitment & Configuration
This is a universal-fit muffler with a 3.00″ inlet diameter, giving fabricators and DIY builders the flexibility to integrate it into a wide range of exhaust systems. It uses new hangers (not included) for mounting, and exhaust tips are sold separately — so you can tailor the installation and finishing touches to match your build. Confirm your exhaust routing, inlet/outlet needs, and mounting hardware before installation to ensure a clean, proper fit.
