Invidia [02-07 WRX] [04-07 WRX STI] Full Titanium Cat-Back Exhaust

The Invidia Full Titanium Cat-Back Exhaust for 2002-2007 Subaru WRX and 2004-2007 Subaru WRX STI is a single-exit racing system built for maximum power and weight reduction. Constructed entirely from Grade 5 titanium alloy using Nippon Steel & Sumitomo high-quality raw materials, it features 80mm (3.15-inch) mandrel-bent piping with cast titanium flanges, a non-resonated mid pipe, and a single 101mm blue-burnt titanium tip. The result is the dry, aggressive titanium exhaust note with extreme weight savings; a silencer is included for quieter driving when needed.
