Track Edition Exhaust
For those who like it loud, go Track.
The Track Edition Exhaust is equipped with the same
precision-engineering as its Touring Edition counterpart, minus the
resonators up front and 180 Technology® resonators in the rear. Instead,
the Track Edition comes complete with non-resonated downpipes and
straight pipe sections -- leaving the integrated x-pipe as the only
filter.
This version is known to get rowdy, and may be too
much for many. For that reason, this particular version cannot be
returned due to sound preference. Prepare yourself.
