Hello guys, I'm currently running my stock h-pipe with cats and SLP LM1 muffler deletes, I was considering switching over to gt500 mufflers with steeda cat deletes for a little more power. I ordered a VMP custom tune for my boss setup and thankfully they gave me two separate tunes, one for cats and one without. Would the catless/gt500 muffler combo be louder than my catted/SLP Axleback combo? The car is my daily driver so I don't want to go too loud on this setup and attract unwanted attention from neighbors or law enforcement.
