It is non-sense like this and mis-information that gets people all freaked out, you do realize that the 4b11T long block is die-cast aluminum with ductile iron cylinder sleeves.
Aluminum(raw) has a melting point of ~933.47 K/~660.32 °C/~1220.58 °F
A catback, even a test pipe and cat back will never even be close to the melting point.

I know the block is made out of aluminum with cast iron sleeves (liner). Let's say "IF" the engine melts, it has to melt down the sleeve before it gets to the block and don't forget the block is water cooled.
Correct me if I am wrong

Most aluminum is very ductile in nature and a hot aluminum pipe, like an exhaust pipe at operating temperature, is even more ductile. Ductile materials NEVER "snap," as this brittle fracture is the result of a very hard and brittle material. Aluminum (again, especially hot aluminum) will break in a ductile failure.. the classic example is a frozen stick of bubble gum vs an 80 degree stick of bubble gum.
You're not giving aluminum nearly enough credit...
Oh and one more thing, the exhaust heats up rather quickly, so you'd have to start your cold car and then launch it within a few minutes in order to have enough engine torque to make it all the way to the cat back and "snap" the cold aluminum.

FYI, for ppl that are interested to build aluminum exhausts http://sccaforums.com/forums/thread/216833.aspx

i used aluminum mainly for weight reduction and heat dissipation. my exhaust tip barely got hot in the summer when i was running the car hard. the stock exhaust tips actually felt hotter than the aluminum tip.
the exhaust is a little low under the axle, but i wanted it to be as straight as possible so it a compromise there. i've driven the car on gravel roads, and its been hit a couple of times, and it doesn't have any damage.
my friend who made the exhaust for me wants to re-do it, but with a custom muffler and titanium. he's currently doing a full header to catback titanium exhaust for an sti, and it looks phenomenal.
all i can say is the car sounds awesome @ WOT.

just wondering if you have to do customizing on the benen tow hook to install it or just bolt on?can you show some pics too how the tow hook installed so that i could compare the underneath of a us and canadian evo.
