Since my muffler is starting to starting to show signs of wear I figured I should replace the headers and cat also. I would like to use stainless steel from header to tailpipe (minus the goofy tip). I'm thinking I'll go with the flowmaster muffler. Where can I find a stainless cat converter and headers? I've looked at the Borla and Gibson application listings but they don't show anything for an 89 Blazer. Who else makes them? I would prefer headers that don't make spark plug changes a headache and will work with a 4 inch lift. Is there any reason not to use stainless for everything besides the cost? Will heat dissapation be a problem?
