GPR Range

GPR Motorcycle exhausts range. Road and race silencers and full exhaust systems.

Unless stated otherwise all GPR silencers come complete with all fittings, link pipe (if required) and are road legal. Road legal nearly always means E marked but in rare circumstances can mean BSAU standard.

Sometimes when new versions of silencers are introduced we do not always get round to updating every listing so if it isn't listed for yours please ask. Generally anything that fits an oval will also be available in GPE, Speedcone and Furore.

Oval or Round

The classic oval and round. Particularly suitable for older bikes or those on a tight budget who still want a high quality road legal silencer. Mostly available in Stainless steel, Carbonox*, Titanium and Carbon Fibre. Generally if we list either oval or round as an option for your bike but not in the material you want it, can be obtained just call and ask for details. All come with a removable db reducer and in line cone baffle. If fitted without these it will perform as a full race can. A lot of options for not a lot of money.

Tiburon

The GPE was designed from day one to look and work just as well as an under-seat unit as it is side mount. Available in the same three finishes in race or road trim. As an unde-rseat slip-on it is called the Tiburon (to add confusion it is available rarely as a side mount).

Ghisa

The word “Ghisa” is used as a slang term in Milan to mean traffic cop. So when our Milanese friends want to warn another rider about a police presence they shout “Ghisa! Close the gas!” So we have created Ghisa to be quiet at low rpm but to still have a great sound and good power when the revs climb and the gas is fully open. Just like the traffic police uniform and the cast iron the name originally comes from the colour is black and is created with a very durable ceramic finish or with a carbon look end cap (sport)

Full Systems

G.P.R. full systems are available for many Bikes. All are made from 304-grade stainless steel, and the purpose is always power. Tapered Headers improve power and torque. Check in the shop area to see if available for your bike can sometimes be specified with a different end can than that listed. Also can be specified as full race spec if road legal is listed. Just ask.
