Hello everyone. I have a 2004 STX F-150 V-8 4.6L. I wanted to know what the best Exhaust would be for my Truck. I want one that gives the best of both Worlds. Power and Sound. Do Performance Exhaust really give that much of an Horsepower Boost? Midas has the Raven. Would this be a good choice or, are all Exhaust mostly created equal? Also are chips expensive? Hard to Install yourself? Do they make a big difference in horsepower gain?

Thanks everyone for your Info.

 

I just recently Purchased a 4.6L STX myself and had Flowmaster 40 Series installed on it. I did not go with Duals, just single muffler and man does it sound good, and perform much better. If you go with the Flowmaster 40 Series you will need Muffler ID # 942541
