We designed our systems with two goals in mind: to produce more horsepower and keep it affordable. We take fully aluminized 16-gauge tubing and use a proven mandrel bending process to form a smooth flowing system that is free of any 'ripples' or 'kinks' that restrict and slow exhaust flow. Made in the U.S.A.Cat-Back Dual Exhaust Systems:
- Low Restriction Aluminized Turbo Muffler
- Split rear dual 3' tailpipes
- Spare tire must be relocated
- Includes hangers and clamps
- Tailpipes exit under rear valance/bumperPart TypeRadiatorBrandJEGSPackage Height9.0Package Width25.5Package Length33.0Weight21.0 PGPart CategoryPerformance PartsOverall Thickness3 in (76.2 mm)Overall Height18.5 in (469.9 mm)Outlet Size1.75 in (44.5 mm)Radiator Cap IncludedNoInlet LocationLower driver sideMaterialAluminumInlet Size (In.)1.5Core Height17 in (431.8 mm)Core Thickness2 in (50.8 mm)Core Width23 in (584.2 mm)Row Quantity2Outlet LocationUpper passenger sideOverall Width29 in (736.6 mm)Tube Size1 in (25.4 mm)Fan IncludedNoTransmission CoolerYesRadiator StyleCrossflowPackage Qty1Package TypeEA
