Since the rockwell hardness of stainless is much higher, can I still expand 0.065 with a regular tailpipe expander that you use w/ a ratchet? If not, what can I use to expand it? I just need to expand 2 3/4" OD to 2 7/8" OD, so only 1/8". Thanks

You can try it...but most of the time you'll just break the expander. Typically stainless has to be done on a hydraulic machine like at an exhaust shop

 

yeah, you can NOT do it with the usual autozone rental piece, but its fun to take 2 in a row back to them after you break em!! (heating the tube with the expander in doesnt make it work any better )

 

Any muffler shop should be able to do it for a few dollars.

 

haha. that must have been fun. I'll take it to Midas and see if they'll do it. I'm making a custom 70mm exhaust for my S2000 but I could only find a 3" inlet muffler so I just need to expand the piping at where it meets the muffler.
