I have a 2000 Accord EX 4 Door. Today i just had someone put on my catback exhaust and header. I drove on the highway and it was fine. I changed and my gaskets and bolts. Before I got home my exhaust made bad rattling sounds like i was drivin without a muffler. What should I do?

 

I would climb under there (with the car securely supported on jackstands) and check all the bolts and make sure all the hangers are doing what they are suppose to do. Or, be lazy and take it back to the guy who did it. If he has any sense of customer sat. then he will be more than glad to get it right. If you were driving it and it was fine and then it started to clank I would say that something loosened up or wasn't tightened down in the first place.

 

Take a look at the heat shields (on the cat as well as the one near the midsection piping) too if you choose to look under there. I'd take a guess that one of those is causing your problem.

 

Thanks fellas it was the cat converter heat shield
