Mustang Flow Path Muffler 2-1/2 Offset In-Center Out
Part Number: FP634
*Reduced back pressure will cause immediate gains in both power & economy. If you modify your engine, for every 8-10% in power increase, you will gain 30% more back pressure, which virtually chokes the motor. Flow-path mufflers use reflection for maximum flow while still maintaining sound control. Instead of a single flow path, these mufflers use multi flow paths, to remain a true anti-reversion muffler. Flow-Path mufflers are made from 16 gauge aluminized steel, they include support rings around inets & outlets. MAC guarantees Flow-Path to outflow Dynomax #17734 for Flowmaster #43553. These mufflers are the smallest in class, come in all popular configurations & measure just 9 wide, 3 3/4 thick & 13 long.
