All relevant fittings and gaskets are supplied. This exhaust offers improvement in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place. This exhaust system has been designed to be easily upgradable to a cat-back or full turbo-back exhaust in the future by purchasing additional sections. This exhaust has a choice of 4 tailpipe options including a 4.5" (114.5mm) carbon fibre tip. The product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product. EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
