Just wondering if there is anyone out there that has had a noise test done on a My05 sti ppp with a de res centre and an afterburner vortex backbox? i know every car will probably test a bit different, but would like to get an idea what sort of db my car is prior to booking a track day and buying a bung.

Thanks for any help.
