why isn't item M6623453 legal in CA.?A shopperJan 01, 2021
Best Answer:Hi, This is a 47 State legal and not allowed for California. You should look for a 50 State Legal for CA. Some states (CA, NY, and ME) now require the use of CARB-COMPLIANT AFTERMARKET CONVERTERS. EPA guidelines do not allow mismatching emission components.

Customer Reviews

The web sitedidn't say that I needed to purchase a gasket/bolt kit to install this myself. All parts should come with the unit, or atleast notify me at time of purchase that they are not included, and tell me what is needed.

Product was exactly what I needed and matched up perfectly to my original equipment
Purchased on Oct 07, 2008
wrote one review and dished it quiet a bit but also praised it,seems they dont want to post it so im writing another one.you cant call it a bolt on if it doesnt come with bolts,you can only get them from the factory as a whole thing for 2 to 3 times what these cost.the gasket was hard to come by and cost a good bit as you could only get it from the dealer as well....a short trip to the local hardware store and some bolts and a few lock washers later its done and no light as of month 3-4.
