and some \'stainless\' systems still seem to get a bit rusty, mostly on the welds. no rust on any part of a Ti exhaust :)

but yeah, sound like death and super light!

Plus they go the most beautiful colours as they go through heat cycles (not that you can see it under the car I suppose) and its so difficult and expensive to weld titanium properly that you know it was built by a quality firm who can afford decent fabricators, not some eBay cheap tat or robot-welded mass produced stuff

My entire ARC titanium full exhaust weighs less than the stainless midpipe that\'s on the car atm, the weight saving is incredible. Titanium doesn\'t corrode or tarnish either, even in road salt, so far more durable than steel and even stainless

That\'s \'cos they use cheap 303/304 grade that doesn\'t like salt, if you go stainless make sure it\'s 316 grade ;) if you can\'t afford the Titanium version that is.

Forget 304, its more like EN 1.4509, was developed for exhaust systems and is ferromagnetic.

Some of the robot welds can be amazing if done right, we robot weld and don\'t even have to linish the edges off to get a clean edge.

How much is Titanium systems new ???
