CTS Turbo Turbo Muffler Delete for B9.5 Audi A4, A5, A6 and Q5 2.0T (2020-2023)

CTS Turbo is proud to release our high flow Turbo Muffler delete for facelift B9.5 Audi A4, A5, A6 and Q5 2.0T (2020-2023). We collaborated with Sheepey Race to create this original product. CTS Turbo and Sheepey Race created and tested this part and we are both very excited to offer this product to our customers world-wide. The Turbo Muffler Delete is a one-piece design, made using precision CAD tools; and is CNC machined in house from 6061 aircraft grade aluminum. Our Turbo Muffler delete replaces the restrictive, power robbing OEM Turbo Muffler, which is designed to reduce turbocharger harmonic noise by introducing air turbulence to the charged air. Our kit installs in less than 30 minutes with standard hand tools and fits perfectly. Simply remove the right side intercooler hose, undo the 3 bolts and replace the factory part with this shiny billet turbo outlet fitting. For those of you that want optimal power and boost response, this T.M.D. is your answer. Features:

• Eliminates factory turbo outlet restrictor for smooth air flow
• Original design, often replicated by other companies
• No CEL guaranteed
• Compatible with factory or upgraded intercooler hoses
• Perfect fit, one-piece CNC aluminum construction
• Designed and made in Canada
• Re-uses factory mounting hardware
