BORLA(r) Performance Industries is excited to tout their talents on the Tundra Crew Max Toyota Truck. BORLA(r) 140238 is a full True Dual, split side exit, Cat-Back(tm) system with 4" bright chrome on T-304 stainless steel tips. It gives 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 T-304 austenitic stainless steel fabrication and, not surprisingly, out flows the stock exhaust. This BORLA(r) dual system even exhibits better fuel economy numbers which, is a nice attribute for a big truck. The muffler contains an internal H-Pipe for increased performance and improved sound. 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.
