A few weeks ago I noticed a blow coming from exhaust so a quick trip down to my local centre, it needs a new mid and rear sections 1z0253609ah and 1k0253209eg but they cant source either part, turns out both are heavily lacking aftermarket support and zero stock of oem in the UK. I even had a exhaust parts specialist on the case and nothing. So the last 2 weeks I've delved deep into info about fitment. The ccza and bga 2.0 tfsi petrol vrs octavia does share the same exhaust from the cat back. You can still buy rare rear box but mid section no chance. So I ended up fitting a aftermarket rear with muffler and a muffler delete mid section stainless Steel 2.5" and they made me a coupler to join them together, problem solved and sound quite nice I must say.

I forgot to mention I've owned the car since new and this was the original exhaust, 2011 and 155k so not bad. The rear section cost me £170 delivered and mid section £200 delivered, fitment and my local high Street centre £70 total £450, alot better than the 1k I was quoted for custom exhaust. I will add some pictures soon.
