Default Motor Sound Package

I de-flapped my car yesterday and the difference is nice. I guess I'm taking the 'baby steps' approach -

1. I disconnected the flaps on the mufflers. Nice sound, but thought a little more sound is appropriate.

2. After about a month (yesterday) I de-flapped. Very nice sound under throttle.

3. Considering the ECS H-Pipe...

The sound difference between flapped and de-flapped reminds me of our old 993 Carrera S with the Motor Sound Package. A deeper more 'growly' sound under throttle. De-flapped is nice.

What sort of gains does one get from deflapping?

More low-midrange airflow, more sound.

Default Hopefully, with my revo tune, that translates to even more low/mid range power...

Time to look for the HOW-TO on this

Default my attempt with bob's help

remove the bolts of the headlight does help a lot. Make sure you disconnect the vaccum tube attached to the horn before pulling the lower airbox out.<ul><li><a href="https://forums.audiworld.com/rs4b7/msgs/98101.phtml">clicky</a></li></ul>
