UK trackday enthusiasts know all about decibel limits! Some of them - PARTICULARLY TUNED 2ZR MOTORS - need a lot of help.
This QP (Quiet Performance) H2 SYSTEM has two noise-cancelling chambers PLUS an additional tailpipe silencer for the circuits with really low decibel limits.
It is time-consuming to build and greedy on parts. The chambers have to be double-skinned to eliminate resonance (dronnnnnne) and I use Acoustafil ZT-1 in the centre section.
EVEN WITHOUT THE TAILPIPE ADD-ON SILENCER THIS IS THE QUIETEST STRAIGHT-THRU EXHAUST ON THE MARKET.
The trackside add-on silencer is held with a 2-bolt flange easily accessible at the diffuser exit. Away from the track, you do not have to meet those decibel limits so you can re-fit either an oval tailpipe/round tailpipe or the twin-tip for a good sportscar exhaust note. Let me know which you prefer in a separate e-mail.
