WARNING: Please note that certain aftermarket exhaust systems in these catalogs may not comply with applicable California laws and regulations, and may therefore be prohibited for use on California highways or roads, or on roads or vehicles otherwise subject to emissions control requirements. Akrapovič exhaust systems for motorcycles mounted downstream of the catalytic converter (also known as “cat-back systems”) are considered “replacement parts” in California by the California Air Resources Board (CARB), and do not require an exemption or executive order from CARB to be sold in California. However, California prohibits the use of any aftermarket exhaust system that modifies, removes or replaces original equipment catalysts, unless CARB has issued an Executive Order as to such part or system. Further, Akrapovič parts or exhaust systems used or intended for use on “racing vehicles” (i.e. a competition vehicle used exclusively for competition on closed-course circuits) do not require an exemption or Executive Order from CARB to be sold in California. However, such parts are prohibited from use on California public highways or roads, even if occasionally used “off-road.”

Full Exhaust system Titanium Muffler with Stainless steel header
This complete exhaust system is constructed with a high-grade, lightweight titanium outer sleeve and end-cap for muffler, with a stainless-steel link pipe and headers. It weighs in at 3.0 kg lighter than the standard stock exhaust. A noise insert is included in the package because the open version of the system has no catalytic converter and was developed for use on racetracks or closed courses only. Designed to integrate with the lines of the bike, the resonator is located under the body, hidden by the lower fairings, and the muffler exits on the right side of the bike. It is finished with an eye-catching heatshield, inspired by those on the Yamaha R6 and R1. Impressive performance increases of 4.3 kW (5.9 hp) at 9,700 rpm and an added +2.9 Nm at 5,500 rpm have been achieved when tested on the Akrapovič dyno against a standard stock exhaust. The racing sound matches the bike’s sporting credentials.
A black-coated aluminium muffler bracket for the R7 without the passenger foot-pegs is available as an option.

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
