I got my Magnaflow muffler welded on (stock piping)about 2 weeks ago and today I noticed a yellow/greenness on the inside of the muffler tip. I tried wiping it away but it does not come easily. Anyone know what it is/how I can get rid of it?

Here's a pic.

 

hum... never seen green...LOL
but just get some rubbing compound and a rag and polish it up... should take it out.

 

lol, dude i have the same muffler as you on stock piping for now, it sounds decent. Anyways I will let you know in another week if I get that same problem, mine was done a week ago!

 

I think mine sounds awesome. Sounds almost stock, but once you get on the gas its a nice deep smooth tone. And alright, that sounds good.

 

alot of stainless steel exhaust components turn golden after they get heated up and used for a little while, but i've never seen green haha i wouldnt worry about it, probbaly just the type of metal they used or somethin

 

Thats reallywierd. Did you try like alcohol or anything to get it off?

 

I first triedrubbing it away with a cloth andwater, then I tired vinegar (I read it somewhere) and lastly I tried CLR, but have had no success.

 

Thats no good. past that the on;y other thing i would do would be maybe lightly sand it, but idunno if you wanna do that to a muffler...

 

Rubbing compound maybe?

 

addiction already said that, lol
