the real reason that a real compression brake isnt offerend is that the head on a 5.9 is not set up for a true compression brake . a true compression brake can be adjusted so it doesnt lock the tires when engaged . this is why you dont see big rigs locking up when they let off the throttle . are new truck we run at work have 500hp cat in them with a 3 stage engine brake and even with it set on the most aggresive setting i cant get the tires to lock . will push you forward in the seat thow .

Does the Diamond plate box deal come with the "smoker" stack kit also?

there is not room under the cowl for a jake brake. if you've ever taken your pushrods out youll know there isn't room for a head that's any taller. thats the reason a jake isn't offered.

ever try a 6 cyl jake while bobtailing in the rain? tires locked for me...hell you can barely even get the valve cover off a 24V....couldnt imagine another 4" or so

I just saw at this website.....
http://www.horsepowerupgrades.com/products.cfm

that they have the stack kits from mbrp....they come in 4",5" and even 6" in flat cut, miter cut and turn out. Lengths of 36" and 48". They offer cat back, or turbo back and you can buy the diamond plate box to cover your piping in the bed. Look pretty sweet, time to start saving money........

Big Deezul

they do look killer
$800 though

$800 ... Please!

Can anyone tell me what a used set of 6" polished stainless, 3' tall, turn out, stacks might be worth? Know where I could price the rest of the exaust from the turbo to the stacks? Thinkin I might just use one of em and have a single stack on the right side of the bed. If the cat converter is removed does the check engine light stay on like on a gasser? I'm guessin it does.

only if you remove the O2 sensor and jet the carbs!! .

i dont think theres a sensor there! so my guess it would be no. but i would like to find out for my buddie dads truck!

Not sure if this works. Its my other post from yesterday. Good info here. The title was ......Stack question.

Diesel fuel emissions do not require any catalyst, so there is no catalytic converter - whatcher lookin' at is the soot trap, or oxidizing converter.

Is a honeycomb without the catalyst = traps exhaust byproducts - soot - so excursions at highway speeds heats the honeycomb, incinerates the soot, and voila! - no emitted particulates.

In theory, of course...............

Also, along with that pre-caution posted above - ya gotta remove every even, and odd, spark plug wire to safely remove the thing.

i dont see these on the horsepowerupgrade website or the DTR shop....can someone confirm if they are still avail.?

gmctd

not trying to take buisness from mbrp, but you can get them a lot cheaper at any big truck parts store. thats how i got mine. from the turbo back w/ tax wa s at $520.00, but i knew a guy there, and i got mine for 256.00. you have to do all the cutting and welding/clamping yourself, but i didnt mind. with a mig it was nothing.
