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.
