So I got a 2.5 and when I put oversized tires on it, my gas mileage went to crap, which is fine because I like the tires but it has made me apprehensive about the other mods I wanted to do.

One being putting a diamond plated toolbox in the back, would that weight effect my truck too crazy? I don't even know how much those boxes weigh honestly

Secondly, a 3" body lift. How much would that kill my mileage?

Also, if I wanted to get an aftermarket catback on my truck and didn't want it to sound like a Civic, what would you recommend? Doesn't need to be loud just a little more noise than it has stock with a CAI.

Thanks yall

 

The lift won't affect it too much. Its the tires that do. If you regear it will help a little bit.

 

Regear a 4 cylinder? I didnt know people did that. Something you can do on your own or get ahold of a shop? What kind of ratios? Thanks

 

The toolbox you will be able to pickup by yourself. It won't affect economy

 

Anybody ever used RVinyl headlight/taillight tints? They're precut for like 30 bucks. Was wondering about the quality and how dark they were?

 

The 4cyl Ext cabs come with 4.10 rear gears. A cheap way to change is to swap in rear end from explorer. Most V6 auto exploders have 3.88. Check the VIN before you buy from the wrecking yard. Just remeber that most off road mods reduce gas milege and the lower gears are going to reduce your off the line excelleration.

 

What size tires you running? You a manual or an auto?
