Yes but even a high flow cat with a midpipe without resonator and with a muffler will produce drone. Begining by Fabspeed valvetronic exhaust, that's what they said on their post and what people report. They also assured me that on their car test, the catless downpipe, midpipe and muffler delete don't make vibrations or unpleasant driving conditions ...
For exemple brands like Armytrix and Remus use 2 small pipes for their midpipe, it helps to contain drone. But remus sound is too "quiet" for me and i don't like the Armytrix sound.
