6. Brand Reputation: Research reputable brands known for producing high-quality headers and exhaust components for the Toyota 4Runner. Consider customer reviews, brand reputation, and warranty coverage when evaluating different header options.
7. Warranty Coverage: Look for headers backed by a warranty or guarantee against defects and premature failure. Review warranty terms and conditions for coverage duration, limitations, and exclusions.
8. Budget Considerations: Compare prices of headers from different manufacturers to find the best value for your budget. Consider factors such as material quality, performance gains, brand reputation, and warranty coverage when assessing overall value.
By considering these factors, you can select headers for your Toyota 4Runner that offer improved performance, durability, and reliability while enhancing the exhaust note and driving experience of your vehicle.
