Are Titanium Mufflers Louder Than Stainless Steel ?

hl0m4n · 10-06-2012, 01:36 AM

are titanium exhausts louder than stainless steel exhausts? comparing apple to apples, if you take a stainless steel exhaust and make a titanium version and put them side by side, would there be a sound difference?

also is titanium more prone to cracking in cold than stainless steel?

I'm thinking weight is the only difference.

i think it would sound the same maybe a little touch different. Just depends on how thick each material is.

sound difference slightly, possible negligible. In terms of weight yes.

Most Ti exhausts I've seen/heard are def louder. They use thin walls so the sound comes through loud and clear. Ti seems to resonate easily, has a ring to it.

OTOH an aluminum exhaust is quiet due to thicker walls, and the material has a flat tone.

Naturally the muffler has a large effect on the sound level and quality, so the above observations are just general traits.

Titanium exhausts do resonate a lot more then stainless giving it a more metallic cadence

I agree with you there Dave.

Typically TI exhausts are used to save weight and they are usually made thinner. The side effect of the thinner walls is typically going to be a louder exhaust. If you take the same car, with the same mods, and and a stainless and TI exhaust, the TI is almost always louder.

really depends on the packing material. A good example is our Titanium muffler we build in house vs a vibrant muffler. The Titanium is quieter due to how much packing material we add. Titanium has a unique note in my opinion. Can't go wrong with it!
