Proven Rear Cannons That Actually Work

[adzR34]

You want twin cannons...here u go.

What do you guys think of Blitz nur spec R? in loudness and cruising drone?

Im using the HKS Drager for GTR33 on my GTT which is quiet on idle, cruise (no drone) and sound wild on top end. Would love to remove the center box to get more less restriction since the rear cannon is already big to muffle the sound. Anyone try it yet.

An update:

The HKS Silent Power system was beautifully made with increased pipe diameter at each flange, muffler etc, but simply way too LOUD. Could only recommend it for a stock turbo engine.

Trust Extreme II presently in use is not as well made, centre muffler has doubtful flow characteristics but it’s a much quieter ride. HOWEVER after it all gets hot on a long drive, the drone starts to re-appear, so again poor muffler packing is letting this system down.

The next step will be a twin hand built system, sick of throwing $$$ away.
