exhaust questions
I noticed a big power loss the other day, it gets worse the higher the rpms get. So i suspected it was a cloged cat. I looked at it after a drive, and it was red hot right in front of the cat. I think this means its cloged, but does anybody else have any ideas.

Have RX-7, will restore

start the car and go to the rear and put a towel (it may bun your hand) in front of the muffler's tips and have someone rev the car. it should blow the towel around quite a bit. if it doesn't move much or there isn't much coming out of the muffler, your cat is prob clogged. usually red in the exhaust means clogged, esp the cat.

...94% correct.
revving slow and power-loss can be the cat...which in your case it probably is. But every RX7 I've ever owned could get the exhaust glowing without much problem.
