When I was doing some reading about that Elantra N fiasco, one of the articles mentioned the test should be done only in modes that are persistent after a shutdown/startup, meaning track mode shouldn't be tested because if you shut the car off in track mode and then start it up, it is now in touring.
Now I don't know how true that is because I couldn't find any information on it. A stock exhaust system should not fail these tests but I feel they are more about revenue generation than actually doing anything. Quote:

CA is totally luck of the draw. I've had cops pass me, see my limo tint and loud exhaust and not care. I've also on the other hand been ticketed for "distracted driving" while I was at a stoplight at 6:45 a.m. on my way to work because I was holding a breakfast burrito in one hand. Unfortunately it's their word against yours and your word doesn't mean jack shit. Oh and I fought this in traffic court and still lost. Even after asking the judge where in the CVC does it explicitly state what I did was illegal. No answer. I then asked if the judge drinks a cup of coffee while driving or if they change the radio station, or even in a manual if they use their other hand to shift. Nope. Still guilty.

Central valley near Modesto Ca. I just got it to pass at the state ref. I had to order 2 small mini mufflers and have them installed just before the muffler. Had about 12" of pipe to use. Even after setting the car back to stock and adding the mini mufflers it still came in at 94db. Barely passing.

[QUOTE=Bodack000;
Right now in Ca if you buy a stock camaro and drive it off lot, get pulled over for loud exhaust it will fail the db test locking you up just like me. Absolute crap.[/QUOTE] Just a thought, but for a stock ZL1 could we just go into the infotainment system and set the exhaust to touring mode, or stealth and override the mode switch? Even if they go through the various setting with the mode selector switch the exhaust note shouldn't change correct? |

I am somewhat surprised, however, that a stock ZL1 would fail a warm start sound test, when cat warmup isn't even a factor. That on a cold start causes the biggest "bark" that is likely above 95 dB, warm starts in tour mode should be mild enough, but who knows, maybe the 2019+ tune isn't as stringent as the 2017-2018 one.

Yes, maybe. I'm a Marine but born and raised here so I'm licensed and registered here but my friends who are active duty keep their vehicles registered in their home states and don't worry about it. A few years back, my buddy was coming to my house and was pulled over by the police in Temecula, down the street from my house. He is licensed and registered in Florida, gave him some crap about his exhaust and tint but ultimately couldn't really do anything. Now if you are not military I am not sure how it would work. |
