Is the magnaflow exhaust system street legal?

Question

I got a ticket, because the cop said it was modified. It's a muffler! It doesn't sound that loud, not like some of those coffee can exhaust systems. I live in the state of california, LA county. Is my exhaust legal? How many decibals is it? It's a 2007 Toyota Corolla.

Answer 1

That is amazing. In California, you are not allowed to modify the emissions system of a car or motorcycle. They have just recently started to enforce this. You can contact Magnaflow, and they will tell you if they are certified to sell aftermarket parts in California. I know you bought it, but that doesn't mean it's legal. You could then ask the people who sold it to you for a refund if you want. It's fitness of merchantability. In other words, they're not supposed to sell you something you can't use for it's intended purpose. Good luck on that one.  

Answer 2

magna flow exhausts are street legal and even CARB certified.  contact magnaflow directly about this, they are based in CA if memory serves.  

emissions systems legally stop at the cat, which is why catback systems are so common.  you do need a special to modify the cat, but from there back it's completely legal to play with as long as decibels stay below 95.

however, from magna flow's website, here is a FAQ that relates to your situation

Question: Are MagnaFlow Performance Exhaust systems legal?



Answer: YES, all of our Cat-Back Exhaust Systems comply with most state and federal laws with the exception of the Magnapacks. (Please note, local laws may vary. Contact your local law enforcement for specific guidelines.) Our products are designed and tested to meet legal sound level limits; however, when used in conjunction with other products (such as air intake systems or exhaust headers), the overall combined effect might cause particular vehicles to exceed the allowable limits.

A new law (27150.2 VC) does not require police to use a sound meter to test for excessive noise. A citation is now based upon the officers judgment. Cited violators may have testing done at a smog referee station.

Also, check with www.sema.org for more info. SEMA is a trade organization of the automotive aftermarket, which has been active in protecting consumer rights.



note the new law and how you can combat it.  if you pass, i'd keep the print out in the car for future overenthusiastic LEO's.
