Hello I just got my new dodge magnum sxt 3.5L V6 rwd I like it but I wanted to know first of all what kind of after market performance muffler should I put , I want more like a loud tone then a deep bass one . second thing for the cold air intake should I just get a K.N cold air intake for a crazy 300$ to get the best performance or there are cheaper but as good cold air intake ( not 30$ ebay ones) ? Third thing is I wanted too put a chip in the car too remove the rpm limit and speed limite.... plus get the best performance so what brand would you recommend for a performance chip , so yeah I wanted to know if you had that car or not what other good mods you would put too for better performance thanks
