This^^.
Also depends on whether its decatted or not.
Decatting adds like 10 dB.
Hi I had to fit bungs in mine very loud without.4ndee wrote:Hey just wondering.I used to have a japspeed on my rev 3 na and I used to love the popping and burble.
It was really loud though.
Now I have a quiet twin turbo exhaust and miss the noise, are japspeeds quieter on a turbo?
