HPM Welded 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.
