G.P.R. Replacement Catalyst

This tube replaces your original catalyst by having a straighter exhaust and improved power.
G.P.R. manufactures its products by hand in Milan after your order is placed.

The tubes are made of SAE 304 stainless steel with excellent corrosion resistance and therefore will not rust. To install it, you need to remove the catalyst and assemble piping structure instead.
You can mount the catalyst replacement with your original silencer or a G.P.R. silencer.

NOTE-Since the catalyst replacement will make your motorcycle exhaust levels illegal. This means that this device is only legal to have mounted for track days.

DISCLAIMER: To achieve the highest levels of quality, GPR hand-makes each product to order. As such, these products cannot be returned, and are non-refundable.
