NNP mufflers.

Hence keeps the mufflers quiet when crushing at low RPM, then opens up the other tail section at higher RPM to allow more exhaust out/louder exhaust sound.

Also, there is a mod to have the gates open all the time to increase the sound of the exhaust all all times instead.

NPP actually

There are two methods- one is pulling the fuse (which yes, would be in the manual- but I'm sure you can find the location in a topic on the forum). Pulling the fuse keeps them open at all times.

Method two is purchasing the Mild-2-Wild switch sold by various vendors on site. That will allow you to control whether it's open, closed, or automatic (as it is now, which means they open at 3200rpm).

Pulling the fuse leaves the flaps open all the time. a quick search will give you the fuse location.

A better idea is an exhaust controller switch. Check http://sunsetorangecreations.com/ for the best selection and prices.

They "both" open and close at the same time. Electronically controlled, vacuum operated.

Much louder when open, can cause drone at lower RPM.

If you get the "Mild-to-Wild remote unit, and you have home link on your visor to operate a garage door opener, you can program the other two buttons to be "Mild", and "Wild", so you never need the remote fob.
I always set mine to Mild as I make the final turn home, to give my neighbors a break.
