Infinity Design S85 Long Tube Equal Length Headers ***Free Shipping in USA***
These are extremely well engineered headers with long primary runners for optimization of exhaust pulse timing. The equal length ensures that exhaust pulses do not reach the collector at the same time creating standing waves. The standing waves slightly reduce exhaust gas velocity and result in the alteration of the characteristic V10 "F1 sound" the S85 is famous for.
Additionally, equal length primaries ensure each cylinder receives the same "ram tuning" effect from exhaust scavenging the cylinder and more uniform power production per cylinder. This allows more aggressive tuning if desired, pushing each cylinder closer to its maximum potential without fear one cylinder is approaching it's ideal combustion efficiency with others significantly lower in power output.
***These headers are in production now and estimated to be complete in by the second week in July. Updates to production schedule will be posted here as well as on M5 Board.***
