bought the car 2 months ago and the exhaust system it has on now is for a honda accord

now idk how they got it to fit.

my problem is when the car sits and i turn it on let it warm up, then i shift it to 1st gear and for a few seconds there is just the exhaust sound a deep sound (sounds nice) but that few seconds later it just start a rattling sound. i got it up a lift today at my friend dad house and i thought it would of been the heat shield over the catalytic converter cuz it was lose but it wasn't
....

any one got any ideas could it be because it the wrong exhaust or something

 

well you said the exhaust was for an accord. SO technically it could be considered the wrong exhaust. I would check the hangers.

 

more then likely it is because the hangers are not correct you might just have to deal with it or buy a new exaust.
