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.

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.

I've personally logged my mpg increases with larger exhausts.

when i had a stack on my 94. it sounded totally different than the under body. but it will. any difference in mpg, no. power, no. did anything change other than sound, no. maybe you just think it did because it sounded different and you were coasting down more hills...

Explain to me how it can change the temp at the manifold a few hundred degrees please. Also explain how you mpg's will increase enough to calculate. Oh right.... If it's posted on the org it must be true... And again for hp, an exhaust might get you 10... Maybe...

95powersmoker, you mean to tell me you haven't heard of those super duper stack kits that get you a extra 93.599 HP? and get you a extra 20 Mpg on top of your current number, and drop EGT's 500 degrees? look on the org, they're out there!
