this sounds good to me but is it really worth the money if u buy it from the dealer? and would u actually get the same results from it? being a stock muffler and all? personally i would not do such a switch but if u like the style and looks from those cars then go for it but better to get after market for the performance. i have a universal HP muffler and custom 2 1\4" piping and it made all the difference. hope this helps.
