HKS Exhaust Evo 8/9
The Carbon-Ti exhaust from HKS is one of the premier systems available for the Lancer Evo. The piping is T304 stainless steel, 75mm (3") in diameter. The muffler is a special carbon fiber unit, capped off with a huge 120mm (4.75") titanium tip. The tip is flame-blued at the end for a jet-engine look. Very distinctive and exclusive!
(Picture above is not the Evo system, but that's what the muffler and tip look like.)
