I getting Magnaflow x pipe with high flow cats, and at the moment i have frpp stringers on right now. my question how loud will i get and how much power will i get from it and is it a good bolt on for my exhaust ? 300 bucks and free install.

With stingers, a catted X will sound good. If you currently have the stock catted H, then a catted x w/hi-flows will be louder. As far as hp/tq gains, you might pick-up 5hp/5tq with the hi-flows.

So this add on to me my car is a plus ? I live in cali so I know when the sniff test comes I can just blot on the old one

You may not need to. Some shops are "mod" friendly and may not look under the car for hi-flow cats.
