Most guys might not think about this until afterwards but I do have a question and I hope you don't mind me asking in your thread.
What do you do when it rains and you have stacks? hang a bucket over them? lol I know some of the big trucks have rain caps but I've never seen them on a pick-up.

I do that (Bucket) on my KW it is a mechanical motor and it's got a few rounds on the fuel screw so it makes alittle soot now. I have a few ruined shirts that have diesel kisses on them, oh well I wear them with pride.

i'm running 5" slash cut stacks. The in cab noise isn't too bad, but i still have a muffler for legal reasons. I've always driven noisy vehicles, so it doesn't bother me, but my tires are noisier than my exhaust at highway speeds.
When it rains, it gets in my stacks. There are enough "engineered in" gaps that the water runs out
. It would take a lot of water to fill the exhuast up to the point that you would be in danger of damaging something anyway. The one draw back is the black spots that appear on the bed after a rain. Rain caps can kinda be noisy going down the road at low loads. .. they tend to klink open and closed.

I think the rain caps on the mitres look cool esp. the 8" ones for the big rigs, if i ever get the 379 ex. hood Peterbilt i want it will have 8" mitres with rain caps.

I have 5" turnouts. I don't think is that bad at all in the cab.

Mine is rather loud for most people in the cab but I have a 3.5" straight pipe without a turbo. Another thing is mine comes up & has to push it's way out to the sides. It doesn't have a Y like the Grandrock kit has. Not a bad thing on my truck because I think it needed some back pressure since it doesn't have a turbo. I just changed from a slider to a one piece rear window & the rattle stopped. It seems like the exhaust is louder now but I love hearing my truck. My Ma & buddy have the Grandrock kit & it's not as bad but they both have 7.3L Superdutys. My truck will just poor out the soot after a good rain so if you ever see my truck in person it will probley be covered in soot.

The sound also depends on the turbocharger. A larger A/R housing will drop the pitch and also lower the overall sound out the pipe.
If you were sitting in the corner of my bed right over my tailpipe you would have one helluva time actually hearing the engine note out the exhaust over the normal road noise I guarantee you. I have YET to actually hear the engine sound out the exhaust pipe with the compound turbo setup. Just keep in mind, that turbocharger selection makes an enourmous difference in tailpipe tone and overall "obnoxiousness". The stock .84 A/R housing is by far the most obnoxious bastard there is. I can't stand to hear them fluttering along with a straight pipe anymore. I would throw the van turbo on in a heartbead before I ran a stock, surging POS TP38 with that housing, IMO.
I personally think that the 38R with the 1.15 housing sounds incredably mean. Very nice sound.
As for stack(s), I'd stick with one. Why be a poser, you've only got one turbine outlet right...

oke:I like the symmetrical look to my truck, the singe stack just looked too out of place to me. But, to each their own. .. i know quite a few people that think stacks in and of themselves are completely stupid.

I love my stack. It's not too loud (on the inside anyway), very tolerable. I'm looking to add a second in the near future...I think it looks a little better than just the one. Plus, it works great when yer trying to some ricer off your butt...
