    Do you have some exhaust leaks? The only clamps I could find that actually worked were the lap joint style band clamps. Before using those mine leaked at every joint and sounded bad. As for the rough running, look closely at the plug wires when it is acting up to see if any are arcing you will probably hear a snapping sound if they are. When I did my install I used Taylor race wires and they lasted about an hour before they started arcing on headers, they were very poorly made and I would recommend using a good quality replacement wire if that is your issue.

    did you keep or delete any AIR parts?

    the reason i ask is maybe you forgot to plug a vacuum line and are sucking in un meterd air.

    Also does the jumping happen during exceleration or while at a stop light or while you are in park?

    It may be your Y pipe hitting the bottom of your car a little, and as far as the sound i was told the tone of it will change once it has been broken in. So wait a few weeks on that but find that vibration because that won't fix itself

    Check and make sure the y-pipe is not laying on the cross brace that is bolted to the under-body directly under the driveshaft.Chances are it is and you will have to modify the brace to get it to clear.
