This black version also has a ceramic coating of aluminium for enhanced thermal and vibration resistance! Features:  - Assembly Instructions included - EC approved - Weighs 1.75 kg - Dual Removable DB killers - All parts needed for mounting are included - Choose whether you want to buy with G.P.R.'s catalyst in the selection menu (if you choose, but you use your original catalyst)   Other information: If you select "Racing Use" included another intermediate tube, mounts / holders and then is not approved for use on public roads. "High level" means that the muffler is fixed higher than the original muffler.   NOTE! G.P.R knows high quality so that is why they begin to hand craft your order after your it has been placed. This then means that customers who want to purchase of the Bolt-ons can only be ordered against advance payment and return policy does not apply
