Fast Intentions Resonated HFC

marcussoori

Wow, VERY quiet. Tony, a question:

1) FI CBE + straight pipes

louder than

2) FI CBE + resonated straight pipes;

both of the above WAY (?) louder than

3) FI CBE + HFCs;

the above slightly (?) louder than

4) FI CBE + resonated HFCs?

To clarify:

Are straight pipes way louder than HFCs?

Whether you look at your two types of HFCs or your two types of straight pipes, does the resonation lower sound level, or just eliminate rasp and hissing? Finally, does the resonation raise or lower the sound pitch?

Thanks!
