Heres my story..
Guys, I don't think there's no way around the raspy sound. Even when I intalled a custom xpipe the rattle was gone. But the exhaust note wasn't the same. I expected it to be louder and have more of a grawl to it .. Now the problem was with exhaust note. The muffler gave me a raspy note. Like the muffler was getting to much air flow. It couldn't handle the power. Causing the sound to be a lil ricey. My exhaust guy that made the x pipe suggested removing the resonator section then going with 2 1/2 flaged resonators (either 12 or 14 ") and still use the Nismo muffler. SINCE I to didn't want to take the look away from my car. This is when my back was against the wall and choose to get a Catback from FI.
Now just a little info on this situation. THE RASP GOT LOUDER! lol the muffer tips don't stick out enough passed our bumper either. Also the xpipe section is 3 pieces! Why not make it 1? (So it can all fit in 1 box to ship was my guess)
The only thing I like is the sound while accelerating. Not happy w spending mad money and waiting 3 months to get it either. Back to the baby rattle/rasp. Its so loud I wanna take everything off and go back to stock and regroup my thoughts.
