I have a set of dual muffler MazdaSpeed exhaust on my RX8, and recently, it's started to turn yellowish in color (I'd imagine its from the heat).

I wanna know if there's a way to renew its shine to the original state. It looks dirty, and I like my car clean.

 

well that same thing happens to the Racing beat cat-backs, and as i dont remember what they said, you might get better answers if you posted this in the Tech garage fourm. just a little fyi

 

and this should help. https://www.rx8club.com/showthread.p...g+beat+exhaust I just searched yellow racing beat exhaust

 

english custom polish is very good
