Exhaust fumes smell bad...could it be the cat?

[kdoggx2o00]

Hey guys, i recently noticed that my exhaust fumes smell almost like firecracker smoke smells. However, there is no smoke coming out of the exhaust. Could this be my catalytic converter? In a previous thread, i talked about a rattling sound coming from the undercarriage when i shifted fast or went over a bump...could this all be related?

Thanks in advance

Could be. You could unbolt it and take a look or take it to an exhaust shop.

Are you sure nothing is leaking on hot exhaust parts? Does your exhaust just 'stink' like a high flow cat, or does it 'choke/gag' you like hks 272 exhaust cam rich idle with NO cat?
