    "Manual says to remove torsion bar for installation on a 99 4x4 K150 GMC Suburban which requires taking wheel off removing shock tire rod yadda yadda yadda. Much simpler to cut the PS pipe in front of the converter install it in two pieces and splice the pipe back together. Be careful where you cut though and make certain your spliced length matches the original. Relatively easy install and far simpler than removing the torsion bar! Allot time for removing the tape from the exhaust manifold end of the pipes though - a necessary evil to protect the unit during shipping. Took over a week to arrive but was quite satisfied once it got here." posted by: Dutch on May 26, 2014
