    07 GP1300R exhaust upgrade

    Hi Guys,

    I am getting conflicting info on weather to do a exhasut upgrade to my 07 GPR. Do you really lose to much back pressure and make the ski go slower? Is the RIVA system my best option?

    Best thing you can do is remove the cat converter instal a "D" plate and a sensor chip to fool the ecm to thinking the cat temp sensor is reading ok. Any other mods to the exhaust other than this WILL cause a loss in HP. Tommy Jordan
