Just the mufflers , I have catless downpipe and intake so I’m sure it’s definitely a little louder than yours would be stock. For me it’s perfect and idle just a little deeper tone , while driving I like that it doesn’t get any louder after about 2,500 rpm it actually gets lower. No cracking no high pitch sound just deep. Noticed while in 6 gear on highway around 70-80 mph around that 2,5000 range when you let off the gas has a heavy tone . But not Obnoxious again once it lower around 2-2,200 rpm or over 2,700 -3000rpm barley noticeably on the highway . I will try to get a Viedo
