List of turbo muffler delete options for the Mk7 GTI.
| Brand | Cost | Performance (Claimed / Proven) |
|---|---|---|
| AMS Performance | $99 | increases overall turbine efficiency letting the air flow out smoothly into the charge piping. allows the air to maintain velocity without a buildup of back pressure inside of the TMD. Drastically Increased Air Flow |
| APR | $158 | “better turbo response” “Faster spool“ “Better power delivery” |
| DFG Tuning | $99 | Yes – “air to flow smoother.” “better flow” / No |
| Burger Motorsports | $89 | not only improving flow flow improvement |
| CTS Turbo | $68 | Yes – “for smooth air flow” ” replaces the restrictive, power robbing OEM Turbo Muffler,” |
| Eurocode | $63 | Decrease turbo spool time increase your turbo response, and flow, |
| Integrated Engineering | $129 | Increase turbo spool INCREASED THROTTLE RESPONSE |
| Leyo Motorsport | $130 | allows greater throttle response |
| Racingline | $130 | Yes – “replaces the restrictive, power-robbing compressor outlet with a smooth, turbulence free air path exiting the turbo.” noticeably better boost response giving a little more power and throttle reaction, all the while being able to actually hear your turbo working. a small but useful power gain is made. |
| ECS Tuning | $86 | |
| Forge | $149 | improve response due to its sleek single billet design that eliminates the restriction and turbulence caused by the OEM part. |
| Spulen | $105 | Reduces airflow restriction Increased throttle response Better boost response |
| 034 Motorsport | $99 | Allows turbo sounds to be audible |
