hey what is the benefit you get out of a full exhaust system I mean from performance catalytic converters to the tail pipe I really like magnaflow? lets say money is not an issue here. but is it beneficial for a 5.4 expedition to have that? I mean headers, catalytic converters muffler all the way. whatis the Horsepower gain? is it worth it?
Not unless you are doing induction and tuning at a minimum or you are trying to get a VERY SPECIFIC sound from the exhaust.
Well I just placed my exhaust on about a week ago. I've had the headers for a while. I couldn't tell you if I got a huge improvement from the exhaust as I've done several things at once. But all in all I think it sounds great and it did help. Before the exhaust and the plugs and the cops I used to get 13.5-14 mpg.
