Point taken Joe, But if your using these systems on the street, Beware! Your 100% liable! Both companys have a disclaimer, off road only!!!! and if a knowlageable insurance adjuster notices that non factory system, good luck recovering any damages period! Neither company claims to have an in house engineer. homework done. I don`t care how good a weldor you are, In real life, welds fatigue, something I would inspect frequently, and if they crack from inside out you`ll find out the hard way. Good Luck
