been thinking factory ones had weep holes , think it might be a good idea to drill some on my dynomax turbo mufflers ..any one else done this ... good idea or not

Why would you need to add weepholes? If you run the engine up to full operating temperature each time you start it wouldn't that remove any condensation in the exhaust system? I have DynoMax turbos and after probably three years now they seem to be fine and show no signs of any rust.

thanks for the quick reply appreciated yeah your right , but over the winter i have the charger in storage , run it ever other week for a 1hour or 2 .... some times water comes out , even after that long

I've drilled a small hole in the lower bends in the ex pipes, havent in the muffs. I think it'd be an excellent idea & I can say I've followed cars in traffic that were gushing copious amounts of water out the tailpipe
