Man, you are wrong in so many different ways.
Where do I start?
You have a lean condition so I don't know why you are messing with exhaust.
Your car is not glowing because it is blocked. It's glowing because the engine is misfiring so bad that the cat is getting filled with raw fuel and overheating. If you continue to do that, you will end up needing a cat because it will melt the substrate. If the Cat is rattling, it, may have already happened. If so, check with an exhaust specialty shop to see if an aftermarket is available.
Concentrate on finding your lean problem. Check thoroughly for any vacuum leaks or leaks in the intake snorkel first. You may need a smoke test to find the leaks.
