I added Magnaflow's for the sound, and was very worth it. The XS headers in combination with the mufflers sounds absolutely perfect. It almost sounds like the G35 stock exhaust note on steroids, lol.

A full custom exhaust doesn't sound anything like a G35.
Delete the mufflers with straight pipes and have full exhaust and you'll have nothing but loudness. So loud your neighbors will hate you forever.
