Stack Concerns
Ok I'm biting the bullet on the stacks.. Couple questions.. Stacks will be 6" Miter flush with the roof so you won't see them from the front.
1) Has anyone confirmed that we need to drill a hole in the 90* elbow before the flex pipe for draining? Is there any notice with a small pilot hole in it? Massive exhaust leak sound at all?
2) Any effects in the car washes. There's a place here that does an awesome job and I'm friends with the manager. My truck fits through the wash just fine but I'm wondering about water getting into the stacks as it goes through. Be the same as driving in a rain storm I presume?

I never had problems with rain with my mitres. I dont have any holes in my exhaust(i fixed it all) and I dont cover them, and ive never had a problem except once in awhile i get a few black spots on box of the truck.
Auto car washes? Mine doesnt seem to fit in those lol. I would imagine there would be no problems, and puttin coffee cans on it probably would not work, and they may not let you in with them on. I would just drive through it once and see the results. I think the exhaust would be enough to keep it out. My truck idling through a heavy rain would be plenty more IMHO to a car wash and ive never had problems.

Thing is they shut the truck off before they run it through the wash machine.. It's one of those auto tracks that pulls you through it.. They run it, I don't.. I just park, get out and let the guys do the work..

I never have any problems with mine I have no holes drilled in the 90 or any where else for the matter and mine are straight cut. The truck sits out side I don't worry about rain or snow I have yet to have it cause a problem and we had some heavy rain for three days straight and my truck sat for two of those days with out starting started fine with out issue the morning I went to drive it.

Well it looks like youll get tons of water down the stacks. It will drain out of the hole, in that case you'd almost NEED a drain hole, exhaust velocity isnt enough to push it out against gravity. you will though, get tons of black soot marks on whatever's behind the stacks, toolbox, and possibly roof. But your truck is black so it doesnt matter. I drilled a hole at the elbow, and it emits a small stream of black smoke when i romp on it, but NO leak sound at all. It's not under pressure therfore won't tick tick tick.
Go for it.

Well I'm working on my stacks (long story...clamps, bed kit, me with 102 degree fever since Sunday, etc...) and just curious if the water soot mess will stain the truck? Toolbox will be behind them and the truck is obviously white with tan bedrails...Will it stain anything when the soot dries?

I don't have a drain hole in my elbow, and don't have a need for one. There's actually enough of a small gap "engineered" into the joint where the flex pipe meets the elbow that the water can run out.
As for the car wash, my truck won't fit in any of them around here. The only concern I might have is if it's the kind that uses fabric that passes over the truck, one of the strips might get caught on a stack and bend it.

stainless will still rust and if it is not compacted (lack of better word) it will start to leak around the flex joints i'm in the middle of changing turbo pipes and flex pipe on 26 (only have 8 left) 2007 cornbinders that all have less than 100,000 miles on them
the biggest problem with flex pipe is people cut the pipe too short and it over extends and cracks/leaks when it flexes
