Downpipe for Mk6 GTI

[stevarm42]

Hi I have a 2012 GTI with BSR stage 1 tune, which gives plenty more punch to an already nice setup. Exhaust is stock as is the intake and filter. I'm seeking advice on whether a catted 3inch downpipe would work nicely with stock catback exhaust and BSR stage 1 tune? I like the quietness of the stock catback. A little more grumble would be ok, but I'm a older guy who leans toward a more refined, rather than a rorty sound. I'd appreciate input from those with more experience.

A downpipe on a stock cat back gives off a nicer deeper note and makes dsg farts a lot more noticeable ... I don't know about bsr tunes but most other tunes will need an upgrade to stage 2 software as you may encounter a CEL with the down pipe installed

Thanks for reply. BSR apparently do not have a stage 2 and anyway stage 1 and bit with downpipe is enough extra grunt for me, otherwise I'm upgrading brakes etc. What is that causes the CEL with a chsnge to a 3 inch downpipe? I'm not across this stuff but I hoped with a catted downpipe and O2 sensors connected up as per stock I might escape this issue?

It's an oxygen sensor that triggers the CEL. You can get a spacer for this O2 Sensor Spacer - 42 Draft Designs

Great thanks for the link. I'm starting to get the picture of how to go about it. Can anyone tell me if my CCZB engine has a different flange at the turbo from the CCTA and CBFA motors? I like to avoid ordering the wrong pipe.

They are all the same - as long as you buy a Mk6 GTI specific downpipe you will be fine.
