ISIS blast pipes. Don't have any good pictures of my exhaust, but this is the same exhaust on a similar car... lol
Super loud on an N/A KA, but sounds sick on my SR. Was a little too loud for daily driving, so I added an Apex'i Exhaust Control Valve. Quiets it down to non-neck-snapping level of loudness. With the windows up cruising it sounds almost stock.
