My ZL1 is pretty loud at idle due to a lumpy cam, long-tube headers, cat delete, and factory NPP exhaust (which bypasses the mufflers at idle and WOT). I like this because it now sounds like a proper V8 sports coupe instead of a soccer-mom Tahoe, but it has the unintended consequence of attracting every type of bozo at stop lights. So, yeah, I roll off the line at about 5% throttle and short-shift at 2000 RPM while letting the other guy in a loud Jetta or Mini Cooper rip off a brisk sprint to 20 over the limit. Hopefully it makes them look like heroes on the 'gram.
Street racing is indeed stupid - it's far too great of a risk to others, and I don't want to go to jail or pay any more than the already-stupid amounts of money my insurance company already charges. A buddy's kid got busting doing rolls on the highway, and is now paying more to insure his Civic Sport each month than his loan payment. Track days and test-n-tune nights are way cheaper, and better tests of performance. (I can spin the tires to 100+ on the street, so the aforementioned bozo in a Jetta or Mini just might walk me with his 6-second 0-60 even if I'm actually trying.)
