I saw the macht schnell post and I couldn't tell how much the sound changed over the dyno.

Also, is there any difference between different manufacturer test pipes? MS or others? Any particular you would recommend?

Most West coasters are running the Macht Schnell Bypass Test pipes. Here's one member's experiences in this thread:

Macht Schnell Test Pipes Installed!! (dyno/video)

Let me know if you'd like a package deal with the ESS E-Flash tune.
