Noise from front end

I have a 97 GTP and have recently replaced front and rear sway bars, as well as outer tie rod ends, as well as the idler pulley on the s/c belt as the pulley was completely gone! I began hearing a noise coming from the front end after I put on the sway bar. It just sounds like the engine is running rough or a vibration from something somewhere. It does look like the new gmpp sway bar is making contact with the exhaust. The noise comes at maybe 3/4 to full throttle, but no noise under light acceleration. Does anyone know what is causing this noise? Is it due to the sway bar or another suspension piece? Is it the supercharger?
Thanks!

The GMPP should clear the exhaust by a few inches. Are you sure you dont have it installed upside down possibly? It should go in like an upside down "V".

I have it in as an upside down v, a guy on another forum said it should form a v with the middle as the low point. All i know is that it is touching the exhaust.

Hmmmm, is your car lowered? Do you have any exhaust work done?

The noise is definitely from the exhaust touching the sway bar. If it didn't do it before, but is now, then it has to be related to the sway bar install. It may not be the bar itself, maybe you didn't get something back together correctly. Did you drop the rear of the subframe while installing the bar? Another possibility is you may have a bad motor mount and it's just now showing up.
