Tubular stainless steel headers.
Sound never looked so good.
Turn the key and the 557 ignites with a classic V8 growl. Dry chambers bark as the twin water pumps compel water through the dual exhaust in a cascading flow. The overboard acoustically attenuated exhaust then settles into a rich idle note with a pleasing RUMBLE. The 3.5" exhaust combined with traditional thru-hub outlets keeps running decibels to a minimum for comfortable cruising. While under the harshest operating conditions, jacketed stainless headers keep temperatures cool while minimizing back pressure, boosting fuel economy and top-end performance. An exhaust system that makes a statement – without overstating it.
