Kia Optima/Hyundai Sonata - CP-E Cat Back Exhaust System

$1,274.95 USD



  • Presenting the CP-E™ exhaust system for the Kia Optima & Hyundai Sonata 2.0T. Although the stock exhaust is quiet and comfortable for daily drivers, the exhaust note is bland. CP-E has designed the Austenite™ Cat Back Exhaust to bolt directly to your stock components or to the CP-E™ QuickPower™ pipe.
  • Never overwhelming, the new CP-E™ sound will grab attention; not from obnoxious noise, but because the sound is exotic and unique. The CP-E™ Cat Back includes dual StealthPipes™ to assist in making this exhaust the perfect tone for your turbo-charged sedan. These pipes keep the exhaust at a nice tone while also eliminating drone. We have also used Ball sockets for optimum adjustment and better sealing at the connections. For the greatest performance and tone, choose both the QuickPower™ pipe and the Austenite™ Cat Back!

Vehicle Applications:

  • 2012-2020 Kia Optima*
