We’ve determined that our Racing Beat Exhaust for the CX-5 is compatible with the Mazda OEM trailer hitch (Mazda part number: 0000-8E-R01 thru R06). We’re aware that there are several aftermarket hitches also available on the market, but we’ve not had an opportunity to test fit/inspect these with the RB exhaust. Although compatibility seems possible with the other designs we’ve reviewed on-line, we cannot give 100% fitting assurances unless we undertake a test fitting. If you’ve installed an aftermarket hitch on your CX-5 along with a RB exhaust, contact us and provide feedback!
