I got the m5230 gta, and the tip are in bad shape, I was thinking about taking the tip off and have the re-chrome since they don't sell them anymore, I this wanting to make sure that the sound in the muffler and not the tips, and that I want mess up anything like performance. And I would have a shop do the work

 

while i'm not very familiar with this specific muffler i somehow doubt that its feasable to just plate a part of a part, not to mention all the prep work which obviously will be required for a good result. and then there is the notion that somebody considered the definition of insanity (no offense) as doing the same thing over and expecting a different result, assuming it was chromed before chances are it will rust again.

how about finding some ss slip-on muffler tips, they either come polished or can be polished if so desired. then you can wirebrush the existing rust off, coat/brush on some rust preventant, slip on the tips. should be good for long.

i got the optional ford ss slip-on tips on my stock gt mufflers, my guess is yours are a different diameter, might be worth checking oreilys, autozone or such.

hope that helps.

 

They not rusted, this dull and scratched up, $50 to take off and weld back on

 

They are stainless steel, not chrome.
All you need to do is polish them.

 

chit, never thought of this...have the gtas as well...pascal, will the polish remove scratches?
