Is the silence a no? I was hoping to upgrade exhaust before purchasing the double d lift and figured maybe I'd get one that doesn't need modded when lift goes on.
YOU HAVE TO CUT,INVERT & ROTATE the Cat in the driverside to have clearance between the arms and driveshaft.Articulate the suspencion before welding.
THE GOOD THINGS ARE NOT EASY
I saw a Jeep video back when the 3.6L came out explaining that the driver side loop (called the trumpet design) was part of the performance increase on the 3.6L since that was the big difference with the 3.8L. Equal lenght exhausts on both sides is surprisingly fairly important for power.
