i know people who have had lower EGTs with stock straight piped exhaust. you don't put exhaust on planing on getting better MPG, if you do you will be very disappointed. the stacks sound good from the outside but get very annoying in the cab. i cant wait to remove my stack.

Absolutely.. in every single diesel I've put an exhaust/dp on I got better mpg's and power. Lets face it.. the stock exhaust, muffler, cat, and down pipe aren't quite what I would call conducive to good power and mpg's.
Yep a straigh-piped exhaust will drop egt's also due to less backpressure. But I know people who've had 4-5" exhaust systems, and upon putting stacks on, they dropped even more in their egt's.

I'd love to see some facts to back your MPG increase as well as EGT decrease when going from exhaust out the back to stacks... As well as HP increase... There is a guy running over 400hp on a stock obs exhaust with a 3" downpipe... The downpipe is restrictive but the rest of the exhaust isn't... You will gain little to no HP from doing an exhaust, your EGT's should drop but will not be significant especially when unloaded. Exhaust out the back or exhaust out stacks won't make one hell of a difference that you can monitor because you take the temperature at the manifold anyway so why would it change temps at the manifold if you have exhaust behind the tire, in front of the tire, or out stacks? I know I saw zero MPG increase with a straight piped exhaust vs stock exhaust. It has nothing to do with how much fuel you burn.
I've personally logged my mpg increases with larger exhausts.

Well go post a thread on the ORG then and the guys that have personally witnessed it will post and at you. They've logged the egt differences between huge stacks and a rear fitted exhaust. Yes, we're talking a few hundred degrees difference.
