Holy heat batman
I put on my cat replacement pipe today. Turned the car on, drove it to the hoist and turned it off. Was on for less than a minute and was barely above idle. 10 minutes after I turned if off I decided to shoot the manifold/1st cat flange with a laser thermometer and it was almost 300 degrees still. I know rotary exhaust heat is extreme but damn, that's crazy. No wonder it's all held on by stainless hardware and thank God I used stainless to put on the pipe. Also explains why the replacement pipe is so thick. I pity the fool who uses anything cheap and thin for their exhaust.

Absolutely. I was talking to a fellow REX owner over supper about em. He said he saw a study done down in texas where they tested aftermark CATs and exhuast, headers etc. SOme of the products life span was measured in MINUTES.

I think that this is part of the reason RB has you re-use the center exhaust pipe with their systems. You can't just go out and buy 1/8" wall tubing anywhere. The stock exhausts on these cars are really very nice. They are just usually rusty and worn out. Thankfully I wirebrushed off my centerpipe and hit it with some BBQ paint. Looks brand new....
