i can look the part number up but it was SI 2.5 in and dual 2.25 out.
I was always under the impression 2.5 was a little large for the 4.0L, but if it works I'll believe you. Also are you running the 40 or 50 series?

i was running a 40 series flowmaster.

first i had a magnaflow SI/DO-2.5/2.25....
thought i could get a better sound with the performance and mpg i was getting
got flowmaster 40 series.(great sound poor performance and mpg)
now....
i now have a borla SI/SO 2.25 just because i got the muffler cheap(free)... 2.25 is prolly a little small for SI/SO its rare someone has it but it is working pretty well performance is good, mpg is ok i saw better with the dual Magnaflow setup.

i think the magnaflow in 2.5 SI and 2.25 dual out if ya want duals, borla just like it would be good too will help the most.

or a magnaflow/borla SI/SO 2.5.

the reason i say borla and/or magnaflow is cause they have the same basic design.


btw, love your interior choice of paint color, that monochrome paint looks pretty good.

When I started looking for ways to improve my mileage I was getting 13mpg on my daily 168 mile round trip commute with 69,000 miles on the stock truck (2003 4.0 5spd 4x4 XLT 4:10 rears) with a tonneau cover. Needless to say I normally drive between 85 and 90 mph and was regularly hitting the speed limiter. Here is what I did.

Brute Force intake
2.5" Flowmaster
Bamachip 93 octane program
Yokohama AVS S/T 285/60R18s on 18"x8.5 Enkei RT6s
tune-up

Now getting between 18.5 and 20mpg with the A/C on driving between 85 and 95 mph... Even with gas prices going up and switching to 93 octane I havenít spent more than $22 per day in fuel. Next up is an e-fan and maybe some undersize pullies if I can find someone who makes a set for the 4.0...

I agree, especially from a heavy 4x4. My all-time best tank is something like ~21 MPG..

I got 27 mpg in my 4.0L OHV with the A/c on coming back to Houston from Vegas. 65 MPH the whole way with 3.08 gearing. And yeah, 249,000 miles cuts down on friction. I also had a load in back with my T-cover.

With my e-fan in for a week, I got no worse than +2 mpg city driving. I have 31's and never got my computer recalibrated so the mpg is off a little and low, so I probably got better than that. According to my truck I got average from city and highway of 16mpg, and just city at 14mpg, up from around 10 or 12 city.

All city driving as of late I'm getting 18-19 mpg each fillup. The E-Fan made a huge difference, basically a 12-20% difference especially when I'm on the highway alot.
I got about 330 miles on one tank awhile back which was 90% highway but I forgot how much gas I filled up with, probably close to empty.

E-fan does make a difference, power is where I noticed it most, just not so much drag on acceleration as there used to be. Of course if you did a "blind" test with 2 Rangers one w/fan one w/out exactly the same setup, you probably can't tell difference!!!
