The RS Evolution Extreme is based on the RS Evolution Muffler with the addition of full titanium tips. A Hybrid muffler uniting the power and free-flowing characteristics of our N1 Muffler with the quiet and discreet sound output of our Hybrid Megaphone Evolution Muffler. The RS Evolution Muffler is a combination of an A'PEXi original patented megaphone piping structure design and larger piping diameters to produce ultimate performance for your turbo-charged engine.
The N1 series muffler has become a staple of the import tuning industry. The N1 was the first of its kind to incorporate the classic angled muffler design that has became so familiar with today's street cars. Born from our involvement in the grueling N1 endurance series, the N1 exhaust system pairs a straight through design racing muffler with free flowing, mandrel bent piping (60.5mm N/A, 80mm for turbo applications). The combination has resulted in dyno proven horsepower and countless satisfied customers world wide. Designed with track use in mind, durability is of utmost importance. The polished SUS 304 stainless steel canister features robotic TIG welding for an immaculate finish and years of reliable performance.
