Scotty I put a Cat-Back exhaust on my 2001 Honda civic ex 4door 5 speed manual a while back and now their is a slight rattling noise on the bottom of the car. I decided to raise the car on a jack and shack the the exhaust for my self and I noticed it would bang against the body of the car where it connected to the catalytic converter. How do I get it to stop rattling? (I noticed when I hit a bump as well it stops the rattling of a while and then when I hit another the rattling comes back)

well, that exhaust did not fit correctly. So try bending some of it or adding extra exhaust support brackets

Ok thank you!

What would I be able to use for support?
