loud exhaust citations

[bbdon]

Maybe they would go to 3/4 of the rpm for max rated horsepower. Example, if max power is at 6000 RPM, they could test at 4500. That sounds reasonable enough.

Of course, the smog police would have to know what the maximum hp, at what rpm, of every car made or sold in the golden state. That's quite a data base.

My guess, is you're correct Don. They just rev up the car until the meter register's 96db, and then issue a fix it ticket. I assume that if the violater doesn't fix the car, then it goes on his or her record as a "mover". But I may be wrong.

Are they going to give citations to the guys with Harleys who have the straight pipes that have a habit of revving their engines? I swear they are louder and more annoying than any musclecar.

[tirebird]

They do write up the Harley's,..although the bike owners I talk to just shrug it off as one of the hazards of owning a loud cycle.

Put some electronic exhaust cut-outs in your exhaust system, that way it can be loud when you want it and quiet when you don't, and they work from inside the car, very conveinent!

The have a much more expansive database then just that.They have databases with pictures of every single smog controlled engine configuaration ever made,and how every smog related piece of equipment is placed right down to the hose sizes of this equipment.They have databases to decode what the original engine is for any smog controlled car ever made,as well as how much horsepower,and pollution every single engine makes.Their database has to go back to at least 1968 with smog related info,and a few years later I think they enacted their own smog regualtions,and only cars with their regualtions were allowed to be registered in the state.I doubt many of the supercars would have even been legal according to their regulations.with the elimination of smog exemption for historic cars in Cali,I am sure they are dusting off the old books to make sure that every 396 camaro and 454 chevelle in their golden state has the correct part number smog pump on it,and the correct vacum hose routing and all that fun stuff.Since there really isnt a market for 50 state legal stuf for cars this old,you can prety much figure that any 60's era car with headers,a hot rod intake,a holley carb where one shouldnt be or even a few missing vacum hoses will be taken off the road by the smog gestopo.

A freind of mine went back to quiet Dynomax mufflers and 2 1/2" exhaust on his Chevelle so as not to annoy the neighbours. On the dyno the car made the same 371 RWHP that it did before. Sounds stock. Looks stock. Isn't stock.

well after reading this thread i'm going down the muffler shop today and install 3" exhaust with a X pipe and 3"dynomax race bullets. this should make some nice sweet noise around here in so. calif

[Chevy454]

If you're using those bullets by themselves you'd better buy earplugs...

Interesting thread! What about this . . .
