- More Information
This QP system is proving very popular with trackday enthusiasts. The large silencer is a 70mm bore, straight-thru design (no power-loss or dangerous back-pressure introduced) withTWO internal Helmholtz resonance chambers (H2 design). V-band connectors at the SDCP/System join and again at the merged tailpipe module to help adjust the tailpipes in the diffuser. Only 2bular.
You see the internal spot-welds at each end holding the plates forming those chambers? Not an easy task, especially on an oval silencer! It's the only 70mm performance system that will get you down to the low 90's decibel readings yet still have a decent sound-track for the road when you remove the Add-ons.

Looking at the V6 'S'/350 layout you can see a larger Silenced De-Cat Pipe (SDCP) compared to the 380/400 series cars. All good for noise-control and combined with the Track-only Add-on silencers, you can be very confident of meeting and drive-by noise limits.
