Okay, I am making a decision to get a bassani off road x pipe with my SLP lm1. Which metal material should I get? I live in arkansas, not up north. The price difference is 50$ so I need to know if aluminum is okay? Or...yea

The aluminium would be fine. But for 50 bucks I may upgrade to the stainless and never worry about it

I know their is not sound/performance difference. Just metal, but someone said if you not gonna keep the car over 5 years get aluminum. I'm just wondering if I should just save the 50$ and buy aluminum or spend 329$ on stainless steel

I would get the aluminum. I live in Michigan, if my car was a dd I would get a stainless one, but it isn't. My BBK aluminum one is fine cause it doesn't see snow, salt, etc.

They aren't aluminum, they are aluminized steel. Its not the same thing. Stainless or GTFO.

Stainless is for longevity and some of these aluminized parts don't even make it 2 years...

Isn't that an aluminized BBK X pipe you have on your old car in the pic in the other thread?

I heard the tin foil ones are the best. Aluminum/ aluminized we were talking about the same thing.

Yep, for something that never sees salt or road crud its one thing. If the car does... give it 2... 3 years max before its toast.

No doubt. He lives in a warm state with little to now snow so he should be OK for a bit with the aluminized pipe

Since when is aluminized steel less resistant to corrosion than regular ol stainless steel?


Corrosion resistance is basically THE reason they coat the steel in ali+silicon.. So What am I missing here?


Salt is a lot more brutal to steel than it is to aluminum..
It also reflects heat better which is always a plus I suppose.


Stainless steel is probably stronger than Aluminized steel, which could make it last longer. I just don't see how it would be more corrosion resistant in theory.

^Because if the aluminized coating gets scratched or chipped off its bare metal and will corrode. Being on the underside of a car, you are GOING to get rock chips on the pipes at minimum. Stainless lasts longer and that is just a fact. If you think otherwise... well sorry you're wrong.

That makes sense. I guess if the coating gets chipped/scratched then the steel is no longer protected. Just trying to understand the reality for myself. There are so many car related myths that I never trust anything I hear unless theres some sort of logical explanation.

I still hear people saying that running 91 will explode your car if it was meant to run on 87.. so yeah. 90% of things I hear are bull****
