Here it holds nothing but pipe — a 3-into-1 junction dimensioned for flow rather than for conversion.\u003c\/p\u003e\u003cp\u003eThat is a smaller change than deleting the box entirely and a larger one than it sounds. The catalyst is the single most restrictive component in any road exhaust, and its substrate is also where a fair amount of the standard system's weight lives.\u003c\/p\u003e\u003ch2\u003eStill the Lightest of Three\u003c\/h2\u003e\u003cp\u003eSpark quotes 4.8 kg for this system, against 4.9 kg for the 60's racing version and 5.0 kg for the homologated Moto GP one. The Grid-O is the lightest silencer in the Trident programme, and the racing pipe saves what a converter would add.\u003c\/p\u003e\u003cp\u003eOn a 660 those tenths matter more than they would on a litre bike. Three point three kilos is a real proportion of what a Trident weighs, and all of it comes off behind the rider.\u003c\/p\u003e\u003ch2\u003eThe Box Stays\u003c\/h2\u003e\u003cp\u003eRemoving the catalyst does not make this a straight-through exhaust. Spark keeps the pre-silencer box, and it is what gives the system the dark, enveloping note the company describes rather than a raw one.\u003c\/p\u003e\u003cp\u003eFor a track bike that is more useful than it looks. A system with a real expansion chamber ahead of the silencer measures lower at a sound check than one without — and a Grid-O without a box in front of it would be a very loud motorcycle.\u003c\/p\u003e\u003ch2\u003eA Championship Silencer, Unaltered\u003c\/h2\u003e\u003cp\u003eThe Grid-O is full titanium with its TIG welds left unground and a titanium grid at the outlet.
