I have a 99 2-door Tahoe , has anyone done a cat forward system on a 96-99 truck ? I'd like to know if it's worth the cost . Summit offers 5 for these trucks from $250.00-450.00 , all stainless pipes and cats . I just had a Magnaflow all stainless dual system made , it's great . In Pgh. Pa. , stainless is the only way to go ,unless you want to replace it every 2-3 years .
