looks good i wanna know did the paint chip yet or warpped from the muffler tips.

No, but it's only about a week old :-) I did the same exact paint treatment to the front fang section about 10 months ago, over 12,000 miles and holding up as good or better then the factory paint :-)

did you think about using Black Plastidip for this work?
Great Job BTW I like it very much..
