Mine doesn't. Before I bought it I researched and some folks said they fit like crap and rub the bellhousing, some fit great like mine so personally, I suggest it. Keep in mind I have ran across folks saying they had fitment issues with their RacingBeat headers as well even though they're insanely overpriced.
Any other questions, feel free.
I was somewhat mistaken, while breaking-in my motor I dared not go past say 3,800 rpm. Now that it is broke-in and I'm driving the snot out of it, it will contact something another, vibrate noticeably and of course be noisy at about 4,300. The vibration makes my seat a massage chair but I don't care much..I've had mine on for two weeks and I'm having a small issue with it. When under high stress he header will make a ringing noise equivalent to the sound you get from pinging a glass. Does anyone else have this issue?
