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 Titanium header
This is an EC/ECE type-approved complete exhaust system constructed with a high-grade, lightweight titanium outer sleeve and end-cap for the muffler, with a stainless steel link pipe and headers, weighing in at 0.7 kg lighter than the standard stock exhaust. A catalytic converter is included in the package, complying with the current Euro5 approvals. There are performance increases of 1.5 kW (2.0 hp) at 9,200 rpm and an added +1.1 Nm at 5,000 rpm when tested on the Akrapovič dyno against a standard stock exhaust. The deep, vivid sound complements the bike’s sporting credentials. Designed to match the bike’s lines, the pre-muffler is located under the main body and is hidden by the fairing, leaving the muffler to exit on the right side of the machine. The system is finished with a hand-crafted carbon-fibre heatshield.
An optional black-coated aluminum muffler bracket is available for the R7 without the passenger foot-pegs.
Catalytic converter is included within the system.

Perfect awesome easy
Love the look on my 2026 zx10r. Recommend
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.
Best store to buy
Always willing to help and with patience
One fine piece of carbon fiber. Light as a feather. Bike rides like a whole different monster
Weight of a feather. Super flickable, launches and rolls are noticeably more aggressive
