i noticed quite a bit of improvement when i replaced the downpipe. seemed to pull harder on the top end.

for pulling your jeep, just get a box after the exhaust and you'll be done. i pull my cherokee up any hill i want at 75mph. the only time i have to slow odwn is if it's hot out; the temp starts to creep up.

i get about 16mpg pulling my xj at 75mph.

it looks like from your avatar you have a camper shell. if it wasnt for the fact that i plan on getting a gooseneck i would buy one. I dont think i get 16 mpg empty at 75 lol

yes, it definitely helps! I'll get 20 unloaded.

yeah that's averaged with mostly highway. i've seen about 22 only highway.
