Cupra K1 2.0 TFSi Cat Back System - WRC SOUND
Available Options
Due to the uniqueness of our products and the way in which they are manufactured, there may at times be a production delay of up to 2 weeks from the initial purchase date.
The BCS Valveless Cat-back WRC exhaust is our loudest option for the Seat Leon Cupra K1 2.0 TFSi, providing you with the maximum possible full-time audible thrill from your Cupra.
The system has been carefully designed to ensure that any unwanted in-car frequencies have been removed, leaving you with a full-on drone-free experience, together with our characterful pop and burble, free-revving sound.
The primary use for the WRC variant system is the track or closed/private road.
As with virtually all of the TFSi engined vehicles, there is very little performance gain to be had from the cat-back system on its own, due to the incredibly restrictive downpipe and twin OEM cats.
If you require more power from your K1 we recommend the 76mm (up to 400 bhp) or 90mm (400 bhp+) downpipe to go with this system.

As the original rubber mount for the center silencer is prone to wear in regards to its ability to support and prevent excessive movement, we recommend its replacement with the upgraded VAG rubber as shown below.
Please note that our system includes a front section which joins the OEM cat closer to the engine than other brands. You will, therefore, need to cut your down pipe just after the cat to enable our system to fit as can be seen in the images.
