Flowmaster has taken the laminar core of our classic HP-2 muffler and wrapped it in a new compact square case. The new Super HP-2 Series muffler offers the same great performance benefits and moderate tone that you would expect from our laminar flow mufflers, now in a new sleek styling. These mufflers are available in either a 409S stainless steel case or a polishable 304S stainless steel case and in sizes ranging from 2.00 in., 2.25 in. and 2.50 in. These mufflers are covered by Flowmaster's Lifetime Limited Warranty.
