I just did mine...But did not polish it and do all the 500,1000,1500 process...Maybe some other time... Got it down to straight SS finish...Looks clean! But at it since 9am til 3pm!!! Fawk!!! Not completely finish nor satisfied with the tips and I only did the rear section behind the mufflers... Shyt! I can imagine the entire exhaust... That would take DAYS!
