Solo Performance Street Race XJ3 Cat-Back Exhaust for 2006–2010 Jeep Grand Cherokee SRT8 6.1L HEMI
The Solo Performance 991712SL Street Race XJ3 cat-back exhaust system transforms the 2006–2010 Jeep Grand Cherokee SRT8 with the 6.1L HEMI into a true muscle SUV, featuring 3-inch mandrel-bent T304 stainless steel tubing, high-flow straight-through mufflers, and quad 4-inch polished double-wall slash-cut tips for dyno-proven gains of 18–25 rear-wheel horsepower and 20–30 lb-ft of torque while delivering an aggressive V8 roar that turns heads without interior drone at cruise.
Handcrafted with full TIG welds and Solo’s patented J-pipe technology that eliminates low-RPM drone, this system is a direct bolt-on replacement from the catalytic converters back using factory hangers and includes all clamps for easy installation. The polished tips fill the factory valance perfectly and the lifetime-constructed stainless steel ensures corrosion resistance even in harsh winter conditions.
