HONDA CRF 450 [2017-2020] - racing exhaust system

The GPR racing exhaust system for the Honda CRF 450 R/RX built between 2017 and 2020 is a high-quality complete solution for racetrack use. This system, consisting of a manifold with ULTRABOMB extension and the new PENTACROSS silencer line, is made of 304 stainless steel and offers an average power increase of 2 HP while simultaneously reducing weight significantly.

Installing the exhaust system does not require any structural changes to the motorcycle. All necessary flanges, bushings and brackets are included and allow direct mounting on the cylinders. For installation, GPR recommends following the included instructions or consulting the tutorials on the GPR website or YouTube channel.

The exhaust system features removable dB killers (noise limiters) intended for racing use. Removing the dB killers is prohibited by law if the motorcycle is used on public roads. Abuse of this regulation on public roads will void the product's warranty and any refund requests will be rejected.

The product is made in Italy and comes with a two-year international warranty. In the event of a warranty claim, GPR offers repair of the original silencer, with return shipping to the GPR factory or the nearest official distributor at the customer's expense.

This exhaust system is not only a testament to GPR's commitment to quality and performance, but also to their collaboration with the MXGP team, resulting in precise and race-ready development.
