I live in Houston Area in Texas, The place is built on a spawn and i drive down to galveston beach every now and then, its a very salty enviroment, i wash my car every weekend because i like it shiny
, and i have taken off the exhaust too fix a couple sqeeks i think i tightened the bolts too tight or something, but i do not have any rust spots yet or notice anything even trying too rust, i dont even have any mud particles on my tubes
, and if you are worried about rust i would just order the kit, the mufflers come painted black already, you can go and buy anti rust paint like rust oleum and spray a few coats on the outside of the pipe, and when you think its good put it on! and let it roar
