I don't mean to be negative here, but there is something not right with the sound. Two of my friends have this exhaust on their sedans for couple of months and I installed mine like a week ago as well and it sounds great. It really sounds like what I heard on other YouTube videos. Your exhaust sound has a lot of rasp. Do you have HFC's or test pipes?

VQ35HR's Y-Pipe is known for 2.5' inch diameter inlet and outlet. But you don't have to stick with HR Y-Pipe, just get any good Y-Pipe that has inlet and outlet of 2.5' inch diameter because that will match with your Top Speed exhaust.
