Give your truck the sound you’ve always dreamed of with a Performance Exhaust kit! The Flow II Stainless (49288) is made from 409 Automotive-Grade Stainless Steel, and has a straight-through, zero-restriction construction with a louvred core wrapped in acoustic fiber. This design ensures great sound with low back-pressure. Our Dual Exhaust kits contain premium 2.5" pipes, with superior-quality mandrel bends that will improve the exhaust flow and may give you the boost in power and fuel economy normally found in much more expensive systems. Our pipes are aluminized to increase lifespan and durability, and are exclusively custom-bent for us in Springfield, MO. These pipes exit under the rear of the truck, parallel with the outside edge of the frame rail. They are designed to clear the OEM-installed receiver hitch and OEM-sized spare tire. The tailpipes are cut into two pieces for shipping, and swedged for easy slip-together assembly. Our system is designed to fit all wheel-base applications, simply trim the tailpipes to fit. This basic kit includes everything from the muffler to the bumper. This kit does not include tips. Fits: 1988-2018 light- and medium-duty gas models of Chevy Silverado, GMC Sierra, Dodge Ram & Ford F-Series EXCEPT '04-08 Ford. Fits only gas applications; fits only applications that came factory with a single inlet muffler! Only the muffler is made by Different Trend. Please be aware: THIS IS NOT A COMPLETE DIRECT FIT KIT. These systems are to be installed by an experienced, professional installer. FABRICATION MAY BE REQUIRED. Any type of suspension modification/wheel and tire altercation may affect system clearances. We DO NOT provide any portion of the exhaust in front of the muffler. Additional parts & fabrication may be necessary and is to be determined by the installer.
