well i just ordered stacks. and i hear if it rains or snows you have to cover them with a bucket or somethin. Im gettin the aussie cut and was wonderin if i have to cover them if its just lightly raining or what. -

I wouldn't think you would have to cover the aussies like you would a miter or straight cut. I'm sure theirs still a chance of rain getting in but it wouldn't be as bad as the mitre or straight cuts. I personally think you'll be fine without rain caps with the aussies. -

i have have a 04 chevy lly duramax 2500HD 4x4 . it has the banks 6 gun, 5in grand rock aussie cut stacks, 4in mpbr cat delete down pipe, no muffler just strait 4in pipe, cold air intake, dual piller pod w/ autometer boost and pyro gagues, 3in body lift, eagle alloy rims with pro comp all terains. and alot more stuff to come though.
just wanna say thanks to cbrahs and sunsetsky for there help hooking me up

The main reason they cover them in bad weather is because if it rains water goes into stack, next day you start the truck up and it will blow some diesel soot out, aint gonna hurt nothin

Where did you get your stacks from? looking to buy a set for my pick up i just cant believe how damn proud they are of them things, christ i ddint think they would be nearly that much. mind me askin what ya paid for them? what siz are they? -

I had straight cuts on mine w/ rain caps and after bout 3 months the dinging of the caps started drivin me nuts. So now i'm runnin mitres and it's rained all week and so far i've havent had a problem. -

the biggest thing you would have to worry about with rain is if it did rain enough in theory it could get all the way up to the turbo and hydro lock the engine...but were talkin and ungodly amount of rain...the biggest thing that will happen is the flex pipe will start to rust out after a few years of rain getting down in there...like mine -

now i have 4in straight pipe right now. can i only go from 4" to a 5" aussie or can i get 6" tips with 4" pipes? -

I think you can add reduces onto the bottom of the stacks to make it work. I know that the bigger grand rock stacks go down to 5" but like I said a reducer should work, but don't quote me on that -

If it rained enough to fill your exhaust system back to the turbo, I think the truck would be under water and the least of your worries -

would a 6" stack have a different sound coming from 4" downpipe rather than a 5" stack? -

buddy of mine found 8'' turns outs and the actual hole that u see is like 11 and 3/4 and the reduced to 4'' but they were very very pricey.. took a BIG bill to get them..
