SCCA T3 Boxster S- Gearing and Exhaust question

[truegearhead]

The Audi 016 transmission is a direct swap and has different gearing. Also the 2.5 and 2.7 have different gearing. If you really want to get fancy an Audi 01E will bolt up and they sell all kinds of gear sets for them. Even straight cut gears. An 01E would require custom transmission mounts and might need axles “work”. Of course changing your tire size also has a big impact

S headers have integrated cats, 2.5 headers have no cats.
