50 Series HD/Big Block/SUV Performance Mufflers

Flowmasters 50 Series™ HD muffler is Designed primarily for today's higher horsepower trucks such as the Dodge HEMI. This muffler will perform well on various vehicles when a deeper, more aggressive tone is desired. This new muffler features a 4.00-inch internal design, which is ideal for trucks with modified engines. It is built from 16 gauge aluminized steel and comes with various inlet/outlet configurations.

The SUV-Performance muffler is a larger version of Flowmasters 50 Series muffler and is specially designed for trucks, SUVs and cars with large displacement engines. This version of the 50 Series muffler features a special tuning chamber which reduces interior resonance.

The 50 Series "Big Block" muffler is Flowmasters largest muffler for tow vehicles, trucks, large SUV and Recreational Vehicles. These mufflers are made for more than just big cubic inch engine applications. It has a very large H-Chamber to reduce the interior resonance in large cab areas of vehicles and enough case volume to handle engines under heavy loads.
