This MBRP exhaust system is perfect for Jeep Liberty owners from 2002 to 2007 who want to enhance their vehicle's performance and sound on a budget. It's great for daily driving, off - road adventures, or when you just want to make your Jeep stand out. The system is made of heavy - gauge aluminized steel tubing, which is mandrel - bent for optimal exhaust flow. It's suitable for those living in dry climates with less precipitation as the material holds up well in such conditions.
