Yoshimura Carbon Exhaust. This system was not designed specifically for the SSR Razkull, but will fit. In fact, we tested several units that wouldn’t fit, and the Yosh was the only acceptable high mount option. Understand you may need to make minor tweaks to get the system to line up correctly, though no modification or comprimise is required at all. Contact us for full details. No refunds or exchanges for this item.
