"The Hybrid Megaphone Exhaust series uses advanced Japanese technology to provide optimal sound muffling while still producing optimal power. The canister is made of the highest grade polished SUS304 stainless steel while the mandrel bent piping consists of high temperature, titanium particle coated mild steel. The oval canister houses a newly designed rolled tip for an extremely high class finish. Interior construction has been fine tuned for even more low to mid-range power. Countless magazine dyno tests have proven the Hybrid Megaphone exhaust to be one of the best all around exhaust systems on the market. As always, all A'PEXi cat back exhaust systems come complete with all necessary hangers, nuts, bolts, and gaskets."
