does any one know if cat back after market exhaust are illegal in california ???

any details pllz reply thanks...

 

anything on a honda is illegal in california

 

Just depends on what kinda exhaust system it is and if it will pass the desiable test and smog on your car my wife's car passed smog with a cat back mugen exhaust system with twinloop rear section

 

so if it passes smog and aint that loud, it can be legal?

i wanna get a megan cat back NA series for my prelude 92

 

anything that is catback is legal just as long as its not that loud or that big its fine it when you take the cat off that is when it becomes illegal

 

has to be 95db or quieter

 

alright thanks

 

x's 2.

 

x3

 

x4


but if the cop is a dick, then is still possible to get a fix/ircorrectable, but you can fight it if you know for sure is 95dB

 

ill probably get one even if they are illegal

 

whats a cat back aftermarket exhaust?

 

it goes meeeeeooooohhhh and MMEEEEEEEEOHHHHHH when vtak cracks

 

a "cat back" exhaust is all the pipe and muffler(s) from your catalytic converter to the tailpipe. it is a must in emissions legal vehicles to avois a ticket if your replacing your factory exhaust. however "true duals" are very cheap and are nothing more than a pipe from the manafold or header, to the tailpipe, no mufflers or cats.

 

please don't spread misinformation. it makes you look foolish and makes all the dumb kids here dumber

 

then how about you enlighten the people on this site?

 

Apparently all i have to do is spell correctly

But seriously a cat-back has nothing to do with emissions, smog levels are not impacted in anyway by a cat-back exhaust. Cat-back refers to the portion of the exhaust system from the outlet of the catalytic converter to the final vent to open air. This generally includes the pipe from the converter to the muffler, the muffler, and the final length of pipe to open air.

The only reason anything after the cat is required, is for local noise level laws, NOT emissions.


Let me break down what he says-
pretty close, and he shoulda stopped here

Now tell me what part, if any, of this makes any sense????

If it is a catback system, it is legal.

It has to be less than 95dB because of noise laws. So what I suggest is that once you buy one, get it tested, keep the paper in your glove compartment, so if cop wants to mess with you and waste your time with your exhaust (whether it be to pull you over or get it tested due to a fix-it ticket) just show the paper that says it's under 95 dB and then the cop will go home crying.

 

Anything post-catalytic is NOT illegal. But, if it is too noisy, then you must take it off. You can have a "straight pipe" after the cat, and it won't be illegal as long as it passes the noise test. Trust me on this one.

 

that sounds like science!

 

blinded me with science

 

Well that is true to a point. Even if you still have that paper that says it passed, that doesnt mean ANOTHER cop cannot give you ANOTHER ticket, he still can give you citation even with that paper in your possesion, BECAUSE The officer does not know if the exhaust has been modified again after that decibal test had been performed. All they need is a visual inspection or probable cause to determine wether if the exhaust has been modified. All the decibal test does is help you write off the ticket, ."this info is from the state ref. I use to work for them".

 

CA. V.C. 27151 No person shall modify the exhaust system of a motor vehicle in a manner which will amplify or increase the noise emitted by the motor of such vehicle so that the vehicle is not in compliance with the provisions of Section 27150 or exceeds the noise limits established for the type of vehicle in Article 2.5(commencing with Section 27200) of this chapter. No person shall operate a motor vehicle with an exhaust system so modified.
