71 Targa - Heat Exhaust Rattle
First the good news: Finally starting to feel better after back surgery and crawled under the car to replace my speedo cable. My speedo, odo work! Haven't worked since I bought the car in April!! Much easier job than I anticipated. Happy day!
When I accelerate hard I get a rattle coming from the exhaust almost like metal flapping. I have a smallish hole in the bottom of one heat exchanger, could this cause the rattle? Otherwise they look OK. It doesn't happen if I accelerate slowly and build speed rather than giving it full throttle. Ideas besides hanging off the back bumper with roller skates while my wife drives?

Check the exchangers for any rust where it could possibly split. That could cause a rattle. Hope this helps. I had a set of exchangers that rotted where the exhaust pipe comes out and it was causing some noise. Good luck.
