A fresh breeze for the Maxiscooter exhaust market is provided by POLINI with this series of exclusive exhausts. Their production quality and surface finishing combine the most modern of designs with excellent quality and all 100% Made in Italy!
This exhaust is available with their black anodised silencer and its optical gimmicks make it immediately noticeable. The black end cap attached by bolts and the small black heat-shield located on the connection between the silencer and downpipe manifold give this pipe a mean race-look. The one-piece stainless steel downpipe manifold is provided with a connection for the lambda sensor.
According to POLINI, this complete exhaust system provides a slight increase in power output and increased overall performance, especially improving acceleration and throttle response.
SlipOn or Complete system/stainless steel construction/without catalyser/black end-cap/EU approval/100% Made in Italy.
SIP-TIP: This exhaust harmonises nicely with the POLINI ECU fuel-injection module (#P1710001). The POLINI tuning kit (#P1400217), which includes a piston, camshaft, valve springs and the ECU fuel-injection module completes the peripheral components ideally.
CAUTION : Due to the very soft suspension on standard scooters, race exhaust systems can quickly come into contact with the scooters frame when fully compressed. The rear shock absorber should always have its spring pre-load adjusted to maximum compression. To be completely on the safe side, a stiffer after-market race shock absorber system should be included in the set-up of your tuned scooters suspension.
