let it breathe, your suffocating your truck. exhaust is the first thing you should do. second would be an intake. heck im getting 13 mpg with my 97 with 215k and always towing, never driven the truck without a load behing it so i dont know what it gets empty

BTW Welcome!!!

Do you have stock tires??

[electro41230]

banshee the tires are stock tires it is a 4x4.

Banshee,
In my reply to your question about the tires. I read the the reply that I posted to your question. It kinda come off like I was being a smart a$$. I didn't mean for it to sound that way. I do apologize if this offended you or anyone else. I am just trying to give as much info on this forum as I can to get the advice that I need about getting better gas mileage out of my powerstroke. Again I do apologize.

No problem whatsoever Electro!!! you didn't come across that way.

I was just making sure they were stock tires since that will throw your mileage way off as well.

I'm sure you are already doing all the maintenance on regular basis???

i have a 99 4x4 350 auto with 115k on it. always check the mileage every fill up. i get 15 city 15.9 hwy, no load.

Thanks electro

someone else will chime in on where they purchased their exhausts....but as far as the 4 or 5 inch discussion.......the only difference is the sound. there is no performance gain by going 5 inch over 4 inch....but you will notice a sound difference between the two........Marc

just figured mine up and ball park 15mpg. on the exhaust, i got from jegs. i've looked at alot since then and i'm startin to believe that one company makes ALL the exhaust and sell's em to other company's that market them as thier own. no joke, look around and compare. yeah i know how rediculous that sound's but how diffrent can one piece of 4" tube be from another? thier all mandrel bent, stainless or aluminized, 4" or 5" and so on. just my off the wall opinion.
