Lightest Exhaust
OKOK let me say one thing right now.
1. Just because it's Ti doesn't make it light on its own.
I used to run a Greddy Ti, which is around 12 pounds or so. Very light, very thin metal on the piping and flanges just to save weight. It's so thin in fact a few rocks dented the piping while driving. Not sure how I managed that.
The ARC Titan I am running right now. Also full Ti, but very heavy in comparison. The metal is much thicker, flanges much thicker. It's got a huge resonator and a huge muffler on it. Therefore it weights in the 20 lbs + department. Still not as heavy as steel, but all these people are trying to say that if it's Ti its superlight are wrong. It depends on how its made.

That explains the info I received from Agency Power although I thougth the weight was pretty heavy but I don't know if it's full Ti or not.: "Our exhaust is a full 3" system. The system weighs 42 pounds and is 20%
lighter than stock. We don't publish the db level on our exhausts."

titanium isnt that much lighter than alum or steal... the lightness comes in the fact that because its so much stronger they can afford to make the walls thinner- thats where the light weight comes from
Titanium is about half the weight of steel per volume. Aluminum 1/3 the weight of steel.
Titanium is stronger then steel though where aluminum is about 1/2 the strength.
A titanium exhaust of the same thickness of steel will be about half the weight. The primary benefit of titanium though is that it remains strong at high temperatures. This allows you to run thinner material without material fatique failure.
Inconnel is another material that is actually heavier then 304L stainless but because it is so much stronger at high temps as well as being highly corrosion resistant at high temps, you can run it VERY thin to drop weight. If you've got loads of money to throw away on having the lightest, most bad *** exhaust in the world, this is what you would make it out of.
I'd still go aluminum though as it's still lighter and you could probably build 10 replacement exhaust for the same price as that one Inconnel exhaust.

The Agency Power I believe is a Ti Canister only with stainless steel piping. So it looks like Greddy and JIC are the lightest so far. The only way I see to make an exhaust lighter than these two is a titanium pip with no muffler section and no resonator. I don't think anyone makes that because it would be super loud and at that point you might as well just have a turn down after the down pipe and not even run the exhaust to the bumper.

But that site carries a lot of exhausts for Evos that are high dollar JDM titanium. Perhaps you'll find a super light one to your liking.
Hahaha
"I'll take one $20,475 exhaust, and can I get a free tee shirt with that?"
The last line should read "This exhaust is a favorite among people with way too much money and way too little car knowledge."

Mines Ti, they have it in 3.14" (80mm) and 3.5" (90mm). Weight is under 9 LBS for the 80mm and just over for the 90mm. It is also not weak like the Greddy. Best Ti welds I have ever seen on a exhaust. It's $2000 plus it will take 4-8 weeks to get from Japan!
