Lighten your Jeep and improve its durability at the same time by replacing the exhaust manifold with this compact 4-into-1 header. Far lighter than the OEM cast iron, it also provides far superior breathing, scavenging spent exhaust fumes from the cylinder head to the exhaust system. In fact, it’s tuned primary pipes actually flow better than no exhaust system at all.
Borla exhaust systems and mufflers are built of aircraft-quality austenitic stainless steel - stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Aluminizing can somewhat prolong the life of mild steel, but coatings suffer at the weld points. T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system.
Note: Only the flanges are not stainless. Borla’s 3/8" or 1/2" flanges are so thick they will never affect the performance or longevity of the system.
