Buying Guide
- What is your intended use? Daily driver, weekend project, or a show vehicle? Choose a kit that matches your goals for tone, flow, and ease of installation.
- Do you need universal fit or model-specific compatibility? Universal kits offer flexibility but may require custom fitting; vehicle-specific kits streamline installation.
- Material matters. Aluminized steel is budget-friendly and durable for most daily drivers; stainless steel resists corrosion and lasts longer in harsh climates.
- What about emissions controls? Look for kits labeled as compliant with the Clean Air Act and ensure no obstruction to emissions devices.
- Installation considerations. Some kits require welding, while others are bolt-on with hardware included. Assess the level of fabrication you’re comfortable with.
