:lol: I was just curious if the exhaust melted or not.

The really funny part is that the first exhaust for the RX8 that I built back in 2005 using stainless steel along with an OE muffler pipe only weighed 9 lbs

Looks like the exhaust held up though.

it doesn't say aluminum, so pure speculation until someone verifies it

however, I've seen plenty that didn't including the previous link to an RX8 specific failure ...

If it never breaks you are good. If it breaks at the worse possible time you could be heavily inconvenienced or down-right screwed. If you think 3 lbs is worth aluminum over stainless steel for a cat back then more power to you. The problem in general is most people use too thick for SS (and/or wrong grade for the manifold/cat pipe) making it heavier than necessary. My entire SS exhaust system with manifold, cat, mufflers, & hangers is under 30 lbs total. The manifold was built in 2006 and is finally starting to give out despite being T321 material. The new manifold/header/whateveryouwannacallit that I hope to build soon will hopefully use Inconel 625 material for the primary tubes. That's the plan anyway.

Wow, I stand corrected.

:lol:, well he was warned.
