I just purchased a new Invidia Q300 Titanium Tip exhaust for my 2013 Subaru STi, and as many of you may know, Subaru's are notorious for throwing carbon out the exhaust due to the horizontally opposed boxer. Currently I use 1Z Chrome & Metal Polish on the OEM exhaust tips, but with the new exhaust having the blue titanium tip, I am concerned that the 1Z will be too harsh. I want to keep the blue titanium tips bright and clean. I am thinking of picking up some P21S polishing soap, will this be a good product for this purpose? Will it be too harsh? Thanks in advance.
