PE mod video of all rev ranges

I made this video for anyone considering the PE mod. Hope it helps anyone who is on the fence. No drone inside cabin.

So this is with catless downpipes as well? Still has secondaries?

Assume you've retained the E90 resonator?

Catless downpipes.
Resonator delete-Replaced with x pipe.
Secondary cats in place.
PE mod-outside perforated pipes replaced with solid pipes. Muffler-to-muffler perforated pipe untouched. All packing replaced.

Sounds pretty good without the resonator! I should delete my resonator too.

If you delete it and put a 2 straight pipes in its place the tone is a little deeper. I noticed that having the x pipe made the pitch a little higher. Almost whining.
X pipe is $30 on ebay

I've heard that vibrant resonators get rid of rasp.

Do you have videos of inside the cabin?
The PE mod with resonator and second cats has no drone but the sound is pretty quiet.

only difference is that you dont have a resonator from the factory and the tips are a little longer
