Is the GPR Dual Inox street legal?

It depends on the exact fitment. GPR splits this range into emissions groups, and we record the status on every product page. Check the product you want before you buy.

Emissions Status	What It Means for You
Meets EPA emissions limit	Legal for street use in the US on a registered bike.
Not EPA or CARB certified	Sold for closed-course competition use only.

Read this before you order. A large share of these fitments are race-use parts rather than street parts. Some also delete the catalytic converter and may need an ECU adjustment to run correctly. Send us your year, make, and model and we will tell you which group your bike falls into.

Frequently asked questions about GPR Dual Inox exhausts

What is the GPR Dual Inox exhaust?

The GPR Dual Inox is a oval-body stainless steel 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 form.

How loud is the GPR Dual Inox?

The GPR Dual Inox 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.

Will a GPR Dual Inox fit my bike?

GPR builds the Dual Inox 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.

What warranty comes with a GPR Dual Inox?

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.

Can I run luggage on a bike with a GPR Dual Inox?

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.
