It's volume is louder with test pipes.
4K is definitely the sweet spot. It doesn't necessarily get exponentially louder at high RPMs. It's more of a gentlemen's exhaust then loud, poppy and annoying. I enjoy this as it allows me to still hear the induction noise. It's the first and last exhaust for my taste
