Polishing SS exhaust pipes

[chiz]

Hi
I'm polishing these ss pipes from a later FJ and noticed the welds that are attaching the steel stubs that go into the head are lumpy and gross and take up quite a bit of area. Not like the clean small welds of the 84 pipe... has anyone encountered the same? and can the welds be ground down a bit? or is this asking for trouble?
Thanks Chiz

A picture or two of the welds would help understand what you mean by lumpy and gross.

Chiz, your mention of welding is puzzling, do your pipes look like the ones below? They are standard SS late model headers.

You can see the bulbous welds on inside od ss pipe

I wouldn't worry about that at all!  "Theoretically" it may be best if those are all smooth and tidy everything - but in the real world there will be absolutely no difference - measurable, perceivable, or otherwise! 

Polish them up - get them looking nice - and enjoy!

Tip: After they are polished up nice and shiny and after you reinstall them....wipe them down with lacquer thinner and a clean cloth....do it twice....that way when you heat those tubes up, you won't burn in any of your oily fingerprints.
The tubes start off shiny silver but then turn to a golden color after some heat cycles.

Hell yea, I ground down those nasty inner welds, just because I could....love my Dremel.

Yes thanks been doing that all through this episode and plan to do what you suggest in the end as well... It's too bad that the pipes were not formed as carefully as I would have liked but they figured they were painting them black anyway.
