2001 Subaru Impreza Exhaust System at Tuners Depot

Designed for hard tuned, street driven vehicles, the PS Revolution''''s exhaust pressure activated "active valve" system provides the hardcore enthusiast with the best of both worlds. The retracting valve is engaged and disengaged based upon exhaust gas pressure. This revolutionary new muffler design allows high powered street cars to maintain a tolerable, and legal, exhaust note at idle and light throttle acceleration while completely disengaging during high throttle, high load situations. Never before has an exhaust system seamlessly fused the streetability of a stock exhaust system and the performance of a low restriction racing exhaust. Like all A''''PEX exhaust systems, the PS Revolution features a high quality SUS 304 stainless steel muffler. Being the standard for performance and reliability, the PS Revolution uses full stainless steel mandrel bent piping for added strength and minimum weight.

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 Apexi's 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. The mild steel piping is treated with our special high temperature titanium particle coating. The N1 is truly THE benchmark in which others strive to duplicate.
