TRK 502 X stainless steel manifolds

Fully manufactured and hand-welded by TIG for impeccable fluid dynamics that allows exhaust gases to evacuate earlier and more efficiently.
The engine will accelerate faster and with more vigor.
The installation of the collectors allows the adoption of more permeable air filters given the greater fluid dynamic capacity acquired, they come out of the heads with an external diameter of 35mm like the standard collectors but have a larger internal diameter thanks to the reduced thickness of the collectors.
Immediately after the heads, they grow conical up to 40 mm and are fed in a 45 mm 2-in-1 to the fitting that connects them to the exhaust terminal.
They can be installed both with the original exhaust pipe and with any MASS exhaust pipe.
The thickness of the steel is less because it is AISI 304 stainless steel, being the most valuable alloy for these uses, it allows to obtain products of almost infinite duration using reduced thicknesses.
At higher revs, higher performance allows the engine to reach the limiter zone faster, while the greater distance between the heads and the 2-in-1 gives more complete low revs.
The weight has gone from just over 4 kg of the stock collectors to 2 kg of those of our production.
