Made of stainless steel to protect the existing tailpipe from corrosion and deformation. Black coating prevents rain erosion.
No welding or drilling is needed, just slide the tip into place on the tailpipe and tighten with a wrench.
Exhaust tip has 4 slits, which can be perfectly fit the size of the existing tailpipe.
The square outlet makes the vehicle more unique and adds sportier look.
