i got an estimate on some exhaust work for as follows: replacing rusted studs connecting the h-pipe to the headers with stainless steel ones ,put my off road H-pipe on, line up tailpipes, and line everything up and make sure there are no leaks anywhere. they said they would do it for 200 bucks, do you think its worth it. also i dont have a lift , its freezing in connecticut right now, and exhaust work is kinda hard working on jackstands in a freezing cold garage.
