Cat-back system is a twin exhaust which was made by CKS Performance (Still have the receipt for £350)
The BMC is apparently a special edition, hence the silver colour as opposed to the normal black one
This is a perfect upgrade for someone with a standard GTi

Exhaust

BMC

Heres a video of the engine in action.. you can hear the subtleness of it, has a nice grunt without being to loud
becomes louder when ur high up in the revs.. so it does not have a constant drone like most exhausts

£300 for both
I will not split the BMC from the exhaust
Will be coming off the car in the next week or so
