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.
