Most probably not. BTW you won't gain anything by changing the x-pipe, keep your original (and your money) and you can decide whether to delete the center catalysts or not, in which case you will change only the sound to more aggressive and maybe a few hp on high rpm but hardly noticeable. The main restriction is in the downpipes.
