I wanna know if there will be a performance gain. Tuners have mentioned that changing it to a high flow cat will gain some HP, considering if you are already FBO and pushing 450+ to the wheels.
Also, if running PE muffler without any cat, will it have a lot of drone during highway cruising?

I wouldn't cut out the secondary cats. It'll just give you a ton of rasp and you'll drone if you have downpipes with a secondary cat delete + pe. So far I haven't noticed any drone with my setup. Very quiet when you want it to be, and loud when you get on it! Oh and it's even more burbly than before
