I went to a car show today something to do and they have awsome barbeque there. i actually got a top 10 trophy witch is pretty cool. anyway there was a yellow challenger srt there it had a freestanding sighn board that listed the mods flowmaster cat back, cold air intake , custom diablosport tune 550 horspower also a lot of mopar litterature for the hellcat . I was leaving and driving home i was behind 2 cars getting on the expressway and he passed me on the left and gave me a rev as he went bye as luck would have it the 2 cars got off and i was free to catch him i got next to him in third in the sweet spot and he gunned it i followed and passed him shifted to fourth and really opened up the gap. it was pretty bad . At the end of the expressway he was yelling thats a 4.6 i said yup stock 4.6. I dont think he beleived me.
