I have been doing research on this for the last week trying to figure out if an H pipe give me the sound I am after. I have the Borla S axle back on my 13 gt/cs. It has a little bit of raspy, poppy sound when I down shift. I dont mind it terribly but have been looking into a way to reduce it a little and get a real nice DEEP burble rather than the raspy. I know X pipes are more "racey" sounding and H are more classic sounding but since our cars come factor with H pipes. Would an aftermarket like Heartthrob, MBRP, or JBA really make that big of a difference? I don't really want/need it to be louder I just want the deep classic sound and lose some of the rasp.
I plan on keeping my cats as well. I don't know if cat back H and over the axle pipes would be an option as well? Other than more volume of exhaust moving through the pipes would going to a 3 in system change the tone at all?
SORRY OP not trying to hijack your thread. Just thought it better to throw it in here rather than open another thread.
