Dosen't look like it's restricting Mike Swauger and Josh Cyrul's performance, these two drver's have proven that many times with there results.
Many of the club racer's here in Cali are using these boxes not for noise but for run time there also starting to use three chamber pipe's.
These motors were built and designed around this combo.
This is the wave of the future so get use to it because one day it will be a requirement for all races.
