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 :c: |
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..

drill a small hole in the bottom of ur 90 so the water has some where to go....mine has been in snow and rain storms without being covered, and its a mittered cut....so no worries.......

drill a small hole at the lowest point. the exhaust will rust faster from the inside out.. otherwise when you start it after a heavy rain it will throw soot filled nasty water 10' up in the air which will rain back down on your truck or whatevers nearby and make it nasty. |
