any droning if only the primary cat was deleted?
Hi there I did my search but couldn't find much info on how much louder it would be if only the primary cat was deleted (both secondary cats and resonators are intact)? I would like to take advantage of the HP gain after the deletion of the primary cat but wouldn't want any droning.
THanks in advance!

Why dont you delete your secondaries too for even more power gain? Keep the resonators? Well, full catless for me didnt drone at much, if at all actually. It drones a little if youre in seventh gear and press the gas but nothing you wouldn't be able to live with. Idk how itll sound, but the primaries are the biggest bottleneck so itll be MUCH louder, not insanely, but louder im sure. I tried no primaries with an x pipe and an h pipe, and both of them only drone at 7th when youre on the has, but still not that bad droning.

Dont wanna go full catless as cannot tolerate the drone at all (my STi is loud enough catless+Full titinium exhaust).
Was hoping it wont drone n only a moderate increase in loudness when flooring it by retaining secondary cats
