Exige S 2ZZ-GE 48mm 4-1 Manifold & SDCP
What's an SDCP? It's a Silenced De-Cat Pipe!
More power = more NOISE and you might need more than one silencer to help meet noise limits. Save your expensive catalyser from track abuse and fit this SDCP to your 2bular 4-1.
It has a unique internal design with no packing materials to burn/blow out. Borrowing from modern firearm silencers, I use different sizes of chambers with different angled baffles to allow noise cancellation of a broad band of sound frequencies. The more revs you use, the better it performs! It is still a straight-thru design and there is no loss of power. If you just have an empty chamber, the gas-speed is slowed dramatically - and that definitely affects power output. People who just drill out their catalysers and run with an empty shell don't realise the damage they're doing to engine performance.
