Quad Adly 500 GPR DB-Eater and K&N air filter?
Hello
I have 2 questions:
1 question: can someone tell me where I can buy the matching DB-Eater for this GPR exhaust: https://images-na.ssl-images-amazon.com/images/I/51ofWjrWCLL._AC_SX425_.jpg
And the second question would be whether this K&N air filter is approved or can be installed legally: https://www.kini-tec.de/Zubehoer-Tuningteile/Zubehoer-Quad/ATV/NACH-BAUTEILEN/Verschleiss-Ersatzteile/Luftfilter/Luftfilter-KN-Sport-Herkules/Adly::1747.html

If the air filter is installed in the original air filter box, then you need to enter nix.
However, if you want an open air filter I see with the registration black.
