I was looking at an aluminized exhaust system for my 1997 GMC k1500 and i was just wondering if that tends to rust? I was wondering so if it does i could paint it with the high temp paint from duplicolor before i put it on my truck to keep it from rusting as bad. Thanks!
I would look into a stainless steel system for your truck. You will not ever have to replace it. Make sure if you put one on they use stainless steel hangers. It will save you money in the long run. They are available I have a 1990 1500 chev and just put one on it. It was not that expensive. Most newer vehicles use stainless steel exhaust.
The aluminizing is supposed to prevent rust however a can of duplicolor is like $5 so you may as well paint it though it won't help much if it rusts from the inside out. Aluminized stuff should last fairly long though whenever you can get it I'd recommend spending extra for stainless, real aluminum or titanium. I work with metal a lot and a lot of steels rust overnight, I'd hate to have anything with that kind of property in my exhaust whether it's aluminized or not.
