Mild steel vs stainless

Standard manifold and aftermarket backbox coupled with either of the above. Which would be louder?

Its not the metal that makes the noise, its more the design and silencers attached.

Cheers. Ive bought one now so will find out lol

Material does have an influence on sound to be fair. Its all about resonance (sp?). For example, more exotic materials such as titanium give very different sounds.

Well im hoping the mild steel is quieter as thats the one ive gone for.

I always thought that mild steel made a raspier sound.

That's always what I've been told too. But they build up rust faster?

Not in my experience. Usually a nicer deeper sound without the tinny feel that stainless can give

depends on the quality,

i've seen a good mild system outlive a shite stainless one.
Got a friend who used to make exhausts and cages for a living, all certified to install cages in race cars, MSA approved etc.

he knew his stuff, and his mild exhausts were always cracking.

moved to Aus now though so no more discount systems

hope not

lol, wrong choice of word really!!

i shall clarify!

His exhausts were the b****cks!

Stainless tends to have more audible resonsance of the two, but as mentioned its far more about the baffles than the material, the material just exaggerates it, overall mild steel IS quieter though if everything else is even.

 

[imprezaworks]

Thats good to know. Trying out an unsilenced centre to see how that sounds.

I had a ktec stealth mild steel exhaust, replaced it with the same system but in stainless steel and the car sounded exactly the same.
