The exhaust system is constructed with 2.50-inch mandrel-bent aluminized steel tubing, includes a specially tuned resonator to help keep the interior tone down to a minimum, then flows into the 80 Series cross-flow performance muffler for a deep muscular tone. The dual 2.50-inch tailpipes split for a true dual exhaust look out the back under the rear valance and are finished off with large 3.00-inch polished stainless steel tips.
