Hey guys, I have a 99 Mustang V6. I want to make my car dual exhaust, so I just ordered 2 Flowmaster 40's. Now my question is, How much is that going to cost me to put in my mustang? I'm talking about labor, extra piping, etc. I know it all depends on the place you take it too, I want to take it to a known place like a Pepboy's or some place like that just to be on the safe side that its done properly. Have any of you done this procedure? If so how much did it cost you and where did you do it.

 

When I did my custom setup it was about 200.

 

What exactly was your "custom" set up? can you be more specific please? & where at?
