Default Temporary Exhaust Volume Reduction

As the title states, I need a way to temporarily reduce the noise from my exhaust.

The SCCA Atlanta division has an exhaust decibel limit of 93 dB and my car runs at 126 dB at WOT, which means I'm not allowed to run the track until I drop the sound. I'm currently running LT Headers, Hi-Flow Cats, and Glass Packs. I don't really want to replace anything for four laps around a course. Is there a temporary method to reducing the sound, temporary in terms of easy on easy off? I've heard muffler caps or something might work, but what are some drawbacks. Any other solutions?

Pipes are 2.5" and the tips are 4" in diameter.

axleback mufflers are fairly easy to install if the original connectors are still on the exhaust.. you could get a set of stock ones and see how much they help and leave everything the same.
Other than that I can't think of anything that would temporarily work.
