Flowmaster HP-2 Mufflers

The Super HP-2 series mufflers offer the same great performance benefits and moderate classic tone that you would expect from our exclusive laminar flow mufflers, now with sleek new styling. These mufflers are a builders dream with a very compact case measuring 4-inches tall x 5-inches wide and are available in either 12 or 18-inch long case, with inlet & outlet sizes ranging from 2.00-inch, 2.25-inch, and 2.50-inches. Super HP2 mufflers feature all stainless steel construction, our exclusive Laminar-flow, and Cool Shell Technologies, which is a huge benefit for use with fiberglass bodied cars. This because the Cool Shell technology reduces the exterior case temperatures dramatically over other mufflers. Super HP2 mufflers are available with either a 409SS case or a polishable 304SS stainless steel case. All Super HP2 mufflers are backed by Flowmaster’s Limited Lifetime Warranty. We also offer larger PRO series mufflers for trucks, diesel and racing applications, along with side-pipe muffler replacements that are ideal for Cobras and Corvette's. All these mufflers feature our Laminar-flow and Cool Shell technologies.
