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.


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, 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. If fitted without these it will perform as a full race can.

Originally developed as the Grand Prix Evolution by G.P.R. during their time as technical partner to LCR Honda in MotoGP. The GP Anniversary was launched in 2019 to mark GPR’s 50th year in business as a motorcycle exhaust manufacturer. Making in one of the longest trading exhaust companies in the world. Available for a wide range of modern sports and naked machines the GPAN is cutting edge modern but with classic good looks and performance that bring a guaranteed improvement to any bike. Unless otherwise stated all versions on this website are road legal but in some cases can be specified as full race.

The road legal versions have removable db reducer. On Euro 4 versions that is protected behind a gauze fixed with “anti tamper” screws. When removed the sound may not be road legal…… Either Jekyl or Hide you choose.

More tear drop shaped than a true Tri Oval shape the GPR Trioval is superb value and very tough. The favourite choice for single and twin cylinder bikes. 100% 304 grade stainless steel. The mirror polished sleeve will continue to look great for years when many other silencers at this price will look and perform as if they are twice the age. Fitted with a removable db reducer.

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.


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.

Available to fit a very wide range of bikes.
