Would like to find out from anyone running these if the additional back pressure these create was a noticeable improvement in torque or hp gains you couldfeel by the seat of your pants.
I tried a set in mine last week. I didn't notice any difference power wise, just lost the super deep rinehart rumble at idle. At cruising speed the quiet baffles hardly made any difference at noise reduction. I pulled them out and put the standard baffles back in, waste of money IMHO.

Thanks in advance
Don't think your really going to see some power gains. The quiet pipes only drop the sound 7db. Thats not much. In my book it's not worth it. If you're looking for more torque, time to spend some $$$
The quiet pipes only drop the sound 7db. Thats not much.
A 7dB drop in sound pressure level represents a sound source having less than half the sound power being generated. That's a significant reduction of energy being released as sound!
It's (just) greater than the difference in clean volume you'd be able to generate with your stereo versus one with an amplifier that produces twice the power output.
In case you were unaware, a 3dB change in SPL is almost imperceptible and a 10dB change in SPL is generally perceived as being either twice or half as loud, depending on the direction of change.
