The Rusty's JL Wrangler 392 Hemi Muffler Skid is constructed using 3/16” steel. The factory 392 "cut out" design muffler is just too cool but it also is very expensive for a muffler. With the Rusty's Muffler Skid you can have peace of mind while off roading that your muffler is protected from the rocks and ruts. The Rusty's Muffler skid has the 392 logo laser cut into the skid and has a logo backing plate that can be custom painted to the body color or any other specialty color. The front side of the muffler skid has the cooling vents cut out in a special way, anybody can do it that way but here at Rusty's we laser cut the 392 logo in front of the muffler and muffler skid so it would let penty of coolin for the muffler and gives it a very cool look.
