what kind of numbers?

I know lots of you have aftermarket downpipes and exhaust on your trucks. Does anyone remember what kind or if any mpg improvement you got, and exhaust with a chip? My friend says that the 7.3 have better results with the mpg with a chip.

i remember that i got about 1.5 mpg better when i started using my edge evolution programmer. with a good economy program from Jody at DP-Tuner i'm sure you would see better than that. the down pipe i could see maybe about .5 mpg or so??? i don't know on the downpipe yet since i'm still stuck with my stocker..

In stock form I was getting about 14-15 mpgs on highway. I now have 4inch turbo back exhaust,afe stage 2 intake and DP-tuner and now I see 18 mpgs highway. Made a big difference for me!

The mods are a double edged sword. If used properly they can and will increase your mileage. I would recommend the DPTuner w/80hp econo tune. Behind that I would go with Tonys chip with an econo burn on it.

When my 95 was bone stock it would get 15-16 mpg. Then the mods began, open air intake, down pipe, straight pipe, 10K and FPR shim. Mileage probably went up to a solid 17-18 mpg. Then went in the 160cc Stg I injectors and a SCMT. Mileage stayed about the same. Then Tony's chip went in and the SCMT went away, I could (driven reasonably) get 18-20 with it. The cold reality of it was that my mileage went back down to 16 cuz it was so damn fun to make smoke.

Stock I got 16-18. Now with my TS and Exhaust, Probably around 18-20 driven reasonably on the 50 or 75hp setting on the chip. Not sure how much the downpipe increases, but I've heard with just the Downpipe you can see 2MPG increase. The chip and exhaust worked for me
