The CTS Turbo Res Delete X-Pipe removes the original resonators and replaces them with an integrated X-pipe, allowing the engine sound to be heard exactly as it should. The result is a deeper and more aggressive exhaust note and the distinctive supercharger whine.

Made from 304 stainless steel and TIG-welded throughout. Lighter than the original part and fully reversible to stock condition.

Features:

• 304 stainless steel
  
• Deeper and more aggressive exhaust note
  
• Integrated X-pipe to balance exhaust flow
  
• Laser-scanned OEM mounting points — direct bolt-on installation
  
• No annoying drone at cruising speeds
  
• Lighter than the original resonator
  
• Fully reversible to original configuration
