harriss Posted March 5, 2018 Report Share Posted March 5, 2018 My passenger side cat converter has gone bad. What size is the exhaust? I would like an easy replacement.....clamp on with minimal welding. Any suggestions? thanks Quote Link to comment Share on other sites More sharing options...
Aldofashow Posted March 5, 2018 Report Share Posted March 5, 2018 Magna flow might make a direct replacement y-pipe with high flow cats my friend got one for his 2005 Tahoe they might make one for these trucks worth looking into. Quote Link to comment Share on other sites More sharing options...
