Marmitta racing SIP ROAD XL per Vespa 125 VNA-TS/150 VBA-Sprint/PX80-150 24166400

The introduction of the SIP Strada XL relegates this class of exhaust to the optical tuning category. If ever an exhaust deserved the term, the SIP Strada XL is truly a wolf in sheep's clothing. This pipe resembles the original article so closely that most have to look again to second-guess its true heritage and potential. It has enormous internal dimensions, very similar to the volume of most bazooka style expansion/muffler systems. The SIP Strada XL is made using a double wall construction. It has been designed with a layer of muffler wool between the solid perforated outer and inner layers of steel to ensure that this exhaust sounds as discreet as it looks. This benefit keeps the neighbors happy while avoiding the necessary attention from the authorities or your local ear doctor following longer tours on your Vespa .

Conclusion: This system offers the performance of the largest " SIP performance" exhausts.

Performance exhaust/five segment manifold/XL version

Steel construction, bulky five-segment collector section, strengthened fixing bracket, heat-resistant paint, plug & play!

Tip: When combining this exhaust with a 166 - 177cc cylinder it is recommended to also include at least a SI 24 carburetor and higher gearing in the set up. For 200cc engines with an SI carburetor the main jet size should be increased by at least ten degrees.
