I want to get a 4inch Ex system turbo back with muffler. I would like pros and cons on aluminized system. Right now I cant see the $ for ss. The factory pipe has been on the truck since it was new and is in good shape. I read on here somewhere that alum would only last app 4yrs. would like some good advice. I dont have snow and ice problems. thanks .

 

I've heard aluminized is better than stainless for rust. I always thought stainless was better though.
