Anybody ever have aluminized pipes rust on them?
I'm very close to redoing my pipes and I've noticed that aluminized pipes are about 50% cheaper than SS pipes. My mufflers are aluminized and have a lifetime warranty. So I figured just to run aluminzed pipes throughout.
Will they last a long time?
Thanks

I had aluminized on a bunch of my cars and they last quite a while, never had any rust out.

At least use SS bolts..... they will save you a LOT of headache in the future. I had to drill out 2 or 3 bolts on one of my collectors (driver's side before cat).

The SS is worth the price, and yes I have had aluminized pipes that rusted. I have even painted my exhaust pipes with high temperature paint and it didn't make any difference in longevity.

What did the '84 come with, stock? I have had my car for 16 years and the factory exhaust system is "untouched". My guess is that it is aluminumized. What ever it is, it's still hanging tough. Stainless steel, ceramic, titanium, and others may last longer, but what do you want to pay? And how long DO you want it to last?

I have aluminized pipes on my 79. I put them on in 1992, along with supercomp headers ( aluminum coated ).
The whole system is still like it was a month after leaving the shop...no rust. ( except the muffler tip's I added later. )
I could not possibly see a reason to spend money on SS unless I planned on showing the car.

Re: Anybody ever have aluminized pipes rust on them? (Raysur)
Question should read "Anybody ever have aluminized pipes NOT rust on them?" Stainless is the way to go if you plan on keeping the car as long as possible. Corvette stock exhaust is stainless from manifolds to mufflers with the exception of the catalytic converter and the muffler internals. The muffler casing is stainless. Tips and end cases are regular steel. There are different grades of stainless and yes, even stainless steel can rust.

ME... and everyone I know who's actually USED them.
No, not to change the subject, but, what aluminum pipe have you been sniffing? :D

Re: Anybody ever have aluminized pipes rust on them? (BBA)
Aluminized pipes will rust. On my winter-driven cars, I get 2, sometimes 3 years from my dynomax intermediate pipe. On my IROC, with the exact same intermediate pipe, it's got ever so slight surface rust after 3 years. The aluminized hold up great in cars that stay out of the salt, but if you take short trips with the car, the condensation will rot the aluminized pipes from the inside.

dynomax intermediate pipe
All I can say is I lived in Va. for 6 years after putting REAL aluminum pipes on my 79...and to this day, their is no rust. I know there's not a lot of road salt in Va except the rare times it snowed/iced...but come on here, I'm not talking about dynomax junk either!

Raysur, Aluminized pipes generally look good when new, then they tarnish or dull out. Dont try to polish them, this removes the aluminized coating and the pipes will rust.
If looks matter I would go ( and did ) Stainless Steel pipes polished or not. Its going on a Corvette!

Is ss heavier than aluminized pipes?
