Putting aside the extremely long wait for the race-exhaust kit. It arrived during the beginning of december & went off fairly swiftly too Zircotec in oxford. For there ceramic endurance treatment along with the header pipes off of my bike. I'll link some images later once I get back home. Follow the link to vimeo for the original exhaust decibel level if you wish. I'm loving the sound & responce I get from the engine & have no regrets getting it or the outer tubing ceramically treated. I was so impressed with the job zircotec did they also got more business by way of doing my entire original system.
