Aluminum vs. Stainless Steel
Yeh, i know a b-pipe doesnt do too much for our car, but are their any major differences flow-wise between aluminum and steel when it comes to exhaust components, regarding b-pipes in particular? Is it just that the steel is better looking and better against rust? I havent ever heard any complaint about aluminum y-pipes not making as much power as SS y-pipes, but then again ive never looked into it until now... edit: okay so i just found that i was wrong about the rust part, its actually the other way around..aluminum does not rust, ss may rust....

It is just cold rolled sheet steel with a very thin (~0.001") coating of aluminum alloy applied to both sides.

I used to live only about 4 miles from work and I would have to replace the cheap aluminized steel b-pipe in my supra due to rust-through every year. I moved about 25 miles further away and the same cheap pipe lasted about four years before I junked the car.

Thats right they can rust from the inward out. For those who live in climates that have bad weather conditions. For those who plan on keeping their cars for a while, it would be smarter to spend a bit more and get SS exhaust.
If I still lived in ontario, I would get SS pipes all around.

stainless steel can rust. but it will rust very, very slowly compared to aluminum. There is no performance difference aslong as there both mandrel bent. Most of the time the only part that rusts are the flanges because sometimes they arent stainless steel.

It is the thread title that is confusing a lot of people.
It should have read "Aluminized Steel vs Stainless Steel"
You will not find an aluminum or aluminum alloy exhaust for a maxima.
The strengths of all the reasonably priced aluminum alloys decrease rapidly with increasing temperature so they are not suitable materials for exhausts.
Subjected to the same environmental conditions, a stainless steel exhaust will always outlast an aluminized steel one. It is the same reason that a stainless steel heat exchanger in a furnace will always carry a longer warranty than an aluminized steel one.
