These headers are the epitome of high-performance exhaust components, meticulously engineered to deliver impressive power gains and unparalleled durability.

The 1st-Racing 09XXLS-04 Exhaust Headers are crafted from premium 321 Stainless Steel, ensuring they can withstand the test of time. This material offers excellent resistance to corrosion, making it an ideal choice for demanding off-road conditions and harsh weather.
