VIDEO 335is DCT with secondary cats removed/resonators

So I finally replaced secondary cats with resonators! Love the sound. Although this video is not the best representation (wheelspin thru third) at least you can hear it! I'm pleased with sound. Very little drone or rasp.

It sound much much better than what I last heard from a vid on the track.

Congrats

That sounds really good

I did this on my DCT as well and got loud pops on gear changes.

The note was a lot deeper than with the cats in place, and this was with the PE rear.

Did you use the vibrant resonators? My "is" with the catless dp's could use just a bit of toning down.

I second that, what down-pipes do you have?
Also, do you get much smoke and or smell?
