Ghisa Exhausts

The GPR Ghisa is a oval-body cast finish performance exhaust made by GPR Exhaust Systems in Italy. GPR cuts each one for a specific bike and year range. It comes in Slip-On, Full System (Race), Dual Slip-On form.

The GPR Ghisa runs louder than your stock exhaust and deeper in tone. Most fitments ship with a removable db killer, so you can drop the volume for street riding and pull it out for track days. GPR does not publish one dB figure for the line, because the number moves with the bike and the system type. Ask us about your model and we will tell you what we have on that fitment.

GPR builds the Ghisa for one bike and one year range at a time. Pick your make from the pills above, then filter by model and year. If your model is not listed, contact us before you rule it out. GPR adds fitments through the year, and we can check the Italian factory catalog directly.

Slip-on Ghisa systems run on the stock ECU map on most bikes. Full systems that delete the catalytic converter often need a fueling adjustment to run right and protect the engine. GPR flags this on the affected products. Tell us your model and we will say which group yours falls into.

Every GPR exhaust carries a 2-year manufacturer warranty against defects. GPR Exhausts Direct is an authorized GPR dealer, and our team files the claim with the Italian factory for you.

Yes, on most models. GPR builds its GPR Tech side cases and top cases in the same factory as the exhausts, so the mounting hardware clears GPR silencers on shared fitments. Check that your model appears in both collections, or send us your year, make, and model and we will confirm the clearance.
