5.7 aftermarket exhaust manifolds

[offthehook2]

Looking to replace the exhaust on 5.7 thinking about going with aluminum manifolds SS risers... stainless marine was my first thought then I priced them ! anyone run Imco thumper exhaust or seaward ? they are almost 1/2 the price ! or anyone have a nice used setup from fresh water ?

Ayuh,..... Welcome Aboard,..... If yer boatin' in the brine, you don't want aluminum anything,.....

get the hard coated option if you go aluminum. you need the anodizing to make them last a few years in the brine.

Im in fresh water only.

Im aware of the problems of aluminum and salt water that's why for a used set I said fresh water only

Thanks
