I’m writing this review to share my real experience with the MORIWAKI Full Exhaust CROSS TWIN BLACK (01810-CG803-00) on a 2025 HONDA REBEL 1100 DCT S-EDITION.The exhaust itself is beautifully made.The finish, build quality, and overall design feel premium. Once installed and running properly, the sound is deep, refined, and perfectly matches the Rebel’s character. Visually, it also looks fantastic on the bike.However, the compatibility and support experience was very frustrating.Compatibility issue not stated clearlyMy OEM exhaust uses three O2 sensors, but this full system only has two O2 sensor ports. After installation, I immediately got an Engine Warning Light with error code P0141.Later, Webike/supplier explained that my bike is considered a European specification model, and this exhaust is only compatible with the Japan domestic spec (Model Type 8BL-SC87).The key problem is: this restriction was not clearly stated in the listing or in the manual. The product description simply says it fits Rebel 1100 / 1100T / 1100 S-Edition by model/year, with no warning about spec differences or O2 sensor mismatch.As a normal rider, I cannot realistically tell Japanese vs European spec.My motorcycle is a Hong Kong official-import unit made in Japan, so I had no awareness it would be classified as “European spec.” I’m not a professional technician, and I didn’t know I needed to check engine/frame codes to confirm spec compatibility. I also didn’t even know the bike had 3 O2 sensors until this happened. From a buyer’s point of view, relying on model/year fitment is completely reasonable.Extra cost to make it usableIn the end, my local bike shop confirmed they couldn’t “solve” the mismatch without extra work. The only way forward was modification (sensor delete / eliminator / ECU handling). I’ve now modified it and it works, but I had to pay unexpected extra costs that were never mentioned beforehand.Final thoughtsProduct quality & sound: excellentListing clarity & overseas compatibility warning: poorSupport / guidance for overseas specs: basically noneI’m not saying the exhaust is bad — it’s great when used on the correct JDM spec bike.But for overseas riders, please be careful and don’t assume model/year fitment is enough. I strongly hope Webike updates the listing to clearly highlight JDM-only compatibility and any required spec checks, so other customers don’t go through the same trouble.Would I recommend it?Only if you can confirm your bike is Japan domestic spec (8BL-SC87).Otherwise, expect warning lights and extra modification costs.View Detail
