what i did was went to a local muffler shop and me and the muffler man (haha don't know what else to call him). but anyway i order from him a magnaflow with one inlet and two outlets and he cut the factory tips off my stock muffler and welded them to the magnaflow. sounds really good, not real loud but noticeable and looks completely stock which is what i was going for. and it only cost me the price of the muffler because he said it was the only crossfire he has ever had in his shop, so he did the labor for free.
