HPM Weled Turbo Mufflers 5-1/2" x 11"
Oval Body
Double-wrapped
welded aluminized mufflers with two baffles and cores (most
configurations). The double wrapped shell helps to give a
quieter sound than single-wrapped welded turbos.
Mufflers are reversible. These have a 5-1/2" x 11" oval
body and are available in 14" or 18" body lengths. These
are our quietest, especially the 18", performance muffler, and
have a nice flow rate for a turbo muffler. The # 1142
was flow tested at 222 cfm at 10" of water.
