The Y-pipe (2-1) collector has a built-in lambda sensor plug and bung to allow accurate engine testing and real-time surveillance and finishes with a V-band clamp fitting to the exhaust line for leak-free and easy mounting/disassembly.
The manifold’s primary pipes have an internal diameter of 40mm. It is important to stress the internal diameter of the pipes because the earlier, cast-iron versions were measured externally and had thicker piping!
The mid-bore, primary and secondary pipes evacuate the exhaust gases and particles with a high-flow velocity rate which permits a quick throttle response and good torque throughout the low-to-mid power-band range which is essentiel for the small to mid engine sizes.
The equal-length primary pipes matched to a long 2-1 collector pipe, recreate a correct back-pressure (or scavenging effect**) to ensure an excellent exhaust flow but also an efficient inlet performance!
Seperate pipe-work to allow partial dismantling for:
– easier initial fitting,
– easier servicing under the car – clutch, gearbox and differential,
– the replacement of any pipework due to accident damage, especially competition and lowered-street cars,
– less expensive expedition to clients as packing is more compact.
⇒ Solid T-bolt and V-band clamps for a secure and leak-proof exhaust line.
⇒ A thick flange for the fitting with all inlet manifold types.
⇒ Stainless-steel ensures a long life – fit and forget!
⇒ Complete kit – all included for home fitting.
