I used to get a real loud harmonic vibration noise under passenger seat area only when cold out <40. Once engine warmed up noise went away ... went away permanently when I installed Solo HFCs

If I have my car backed up against a wall, and do a cold start up, I can hear the NPP rattling a little until the RPMs drop down to normal idle. When I started it in front of a buddy who owns a Corvette with the NPP exhaust, he commented that his sounds exactly the same.

The removal of the guide tabs I posted above completely fixed my issue.

If any of you guys can post up a pic of the location of those metal tab guides, that would be great!

I may get mine on a lift this weekend to do my brake lines, so I'll look then and take pics if I find them

Exhaust Rattle Noise June 19, 2014 On some 2010-2014 Camaros, a rattle noise may be heard coming from the exhaust system. It may sound like the noise originates from the transmission area. If a noise condition is being addressed from underneath the vehicle, first strike the exhaust system with a rubber mallet or a deadblow hammer. If a noise is heard, inspect where the two front exhaust band clamps join the front catalytic converter assembly to the rest of the exhaust system. (Fig. 11) Fig 11 This joint is called a Torca coupling. In this coupling, a small alignment tab is welded onto the exhaust pipe. A band clamp is positioned around the joint and slid toward the rear of the vehicle until a notch in the band clamp is positioned around the alignment tab. This ensures that the clamp is properly positioned on the exhaust before it is tightened. With this clamp in position, a J-shaped clip slides up and over the alignment tab to lock the clamp into position on the pipe. (Fig. 12) Fig 12 In some cases, a rattle noise may be heard coming from this coupling. The noise may be due to the J-shaped clip rattling against the exhaust pipe or from the alignment tab that was originally welded on the exhaust pipe becoming separated from the exhaust pipe. If a noise has been confirmed from the coupling, inspect the exhaust system for any obvious damage or looseness in the related components. If nothing is found, bend the J-shaped clip away from the exhaust pipe. If the small alignment tab is found to be loose, completely remove it from the exhaust pipe. This can be accomplished with the use of a regular screwdriver. Make sure the J-shaped clip will no longer contact anything that may cause a rattle noise in the future. (Fig. 13) Fig 13 - Thanks to Matt Bierlein If this is what your talking about... Peace, Brent
