I have a 04 ranger 4.0L SOCH and i am thinking about putting in a flowmaster muffler #942043. Will this muffler affect backpressure or anything else. I had some guy tell me" it will eventually affect the motor, cause the motor is tuned to run with the stock muffler". is he right?
blah, run the flowmaster, youll be fine. I run them with ZERO cats and my trucks ran/run great!
