View Full Version : 7.3 powerstroke exhaust

10-18-2020, 07:41 AM
I've had my truck for 2 years now, and now that I've decided I'm going to keep it for a long time I thought it would be nice if I did a little upgrading (https://carwrenching.com/best-exhausts-for-7-3l-powerstroke/). I have a 2003 F250 crew cab with the 7.3 engine. What’s the best exhaust for 7.3 powerstroke for performance and fuel economy? I am wanting to slowly do the exhaust, then cold air intake and then a chip of some kind. Are they all the same besides what they are made of? I am only getting around 13 MPG so I am wanting to try to get that up some. Is straight piped or a muffler better or is it personal preference? Thanks.
