Price and Warranty

Price was a factor in my decision, but I didn’t want to sacrifice quality. I compared prices but focused more on the warranty offered. A good warranty gave me confidence in the product’s durability and the manufacturer’s support if issues arose.

Final Thoughts

Buying a catalytic converter for my 2013 GMC Terrain was an important decision that affected my vehicle’s performance and compliance with environmental laws.
