Problem with o/r X-pipe 03 Cobra

[Pitboy]

I just installed an x-pipe on my '03 cobra (supercharged) and it is running like crap. I read the posts about the MIL eliminator but my check engine light has not come on yet. I did start the car a couple of times with just the x-portion of the pipes connected and no mufflers to check for leaks at the shorty headers and the x-pipe. Then I connected the rear portion and started it up. It was definitely louder and had that "tingy" sound that flowmasters typically make. But then as I drove out of my yard I heard it sounded like it was pinging at only about 2500-3000 rpms. WTF!!!! Is this all part of the MIL eliminator??? I have read several people have problems with these MIL Eliminators not working properly. I read you can just make one for about a buck how do you do this so I can see if this will fix the problem before spending $60 on a BBK MIL Eliminator. Any help would be greatly appreciated.... Also do I need to maybe unplug the battery to reset anything??? I dont have one of those trouble code computers....

sounds like an exhaust leak. double check everything and make sure its all tight. disconnect the battery too for 30min or so w/ the drivers door open and see if that helps.

I know its not an exhaust leak I ran it while I was under it and felt all the connections to check for even the smallest leaks. Have you any experience with these Mil eliminators?
