Buying advice

When buying an exhaust flange, prioritize material (stainless steel for longevity), compatibility with your pipe diameter and bolt pattern, and whether you need a full kit. Check reviews for fitment on your specific vehicle. For budget repairs, a simple gasket may suffice, but damaged flanges require a repair kit or new flange.
