How difficult is it to install these myself? is it pretty easy to install but just follow the instructions?

 

not hard at all just be carefull with the 02 sensor

 

Very easy. Where you live, you probably won't have to worry about rust, however, if the bolts connecting the stock downpipe to the midpipe are rusted, there's a good chance that you'll either need an impact to get them off, or just cut them.

 

i live in ventura, ca. does rrm send instructions with the products or if not can sombody please give me something that i can at least follow.
