So i just put a used MAC exhaust on my car, it had a couple leaks so i took it too an exhuast shop got them to patch it up. Now while its sitting at idle it sounds awesome but when i start driving around i can hear this clunk sounds coming from the rear every few seconds, any idea what it could be?

So it turns out my car is misfiring on one cylinder, i can ear a very quiet clicking sound coming form the right exhaust pipe, and it pops at idle and just above but above 1500rpm it doesn't seem to misfire, any ideas? bad plugs?
