In Germany the noise modified OEM exhaust makes with stock cats etc. is already borderline.
If you are already close to a noise violation then dont do it. I have oem mod with secondary cats removed and its a decent amount louder than just the oem mod. I would imagine removing the primary cats would increase volume even more.
