BORLA Performance Industries is excited to tout their talents on the Tundra Crew Max Toyota Truck. The plan was to develop a full BORLA dual exhaust Cat-Back with split side exit. The BORLA system (PN140238) filled the bill, giving the Toyota a great look, pure performance V-8 growl and a nice performance kick. The full dual system even weighs less than the factory single system, thanks to the lightweight stainless steel fabrication and, Not surprisingly, out flows the stock exhaust. This BORLA dual system even exhibits better fuel economy numbers which, in these times of $3+ a gallon fuel, is certainly a nice attribute for a big truck. BORLA, the original pioneers of high quality, T-304 stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy -- all with an easy bolt-on installation. And backed by an unsurpassed written million-mile warranty.
