I have the Greddy Titanium exhuast and love it, but when I left it with a local shop, it was completely blue, entire catback cept for muffler. How can i bring it to the original luster?

 

Dont get it hot.. ?
If you want it to stay that color, your going to have to have a seperate peice fitted on top of it to hide the blue (have a look at most harley exhaust pipes)

 

i love the blue, makes it look race

 

Soon as I get my Ti exhuast bolted up I'm gonna have someone time me on getting it completely blue!

 

sorry but did you just say "makes it look race"???

 

hahaha, ooops.

i ment to say racy, cool, trick and the like. if you've ever seen the exhaust on say a motoGP bike or somthing their all blue purple with welds poking out and such. give it a sortof hand crafted look i think

 

The coloration is caused by oxidation brought on by heat. You could try using steel wool or scotchbrite, but the instant you run the car again, the blue coloration will return.
