Setting a budget helped me narrow down my options. While I wanted quality, I also looked for kits that offered the best value for the price. Remember to consider the cost of installation and any additional parts you might need.

Warranty and Customer Support

Lastly, I checked if the manufacturer offered a warranty or customer support. Knowing that I could get help or a replacement if something went wrong gave me peace of mind after purchasing the exhaust kit.
