The HKS Legamax Premium Muffler for the Lancer Evolution X features a fully polished, stainless steel 304 muffler and piping mated to dual 110mm rolled Titanium tips. Legamax Premium is currently available as a rear muffler section and is designed to bolt-on to the factory mid pipe. Initial testing with the rear section produced 5 RWHP. An optional SUS304 mid pipe has completed development and will arrive to the North American market soon. A full 75mm cat-back exhaust system is currently under development.
