Yes, even the LS1 makes the noise as well as the 4.8's,5.3's, and the 6.0's. I work for GM and it used to piss me off every time I started my car and would here it. They said there was nothing you could do for it so I put on my l.t.'s and loudmouth exhaust and it's not nearly as noticeable.....this just happens to be a 1550.00 + solution.. :willy:
