Turbo muffler delete for K03 turbo

Featured Replies

Hey all,

Newbie here and just looking for advice. I have an early 2007 A3 8P I'm slowly working on getting in good running order as well as aiming for an OEM+ build to learn more about cars.

This weekend I attempted to install a turbo muffler delete, however once I get in there I realised the bolt patterns were completely off. Does anyone here know if there is a turbo muffler delete that would fit this pattern? Everything I search for is coming up with the symmetric bolt pattern, not the asymmetric. Photo for context, left is OEM and right is the incorrect delete I purchased.

Any help would be greatly appreciated!!

So.. update on this incase anyone out there comes across this thread:

  • There are 2 variations of turbo for the early A3 8P's

  • early versions (like mine, with the asymmetric bolt pattern on the muffler) were manufactured by Borg Warner

  • later versions use a IHI turbo (which uses the symmetric bolt pattern on the muffler)

  • There is still a muffler delete out there, RTMG maufacture one which looks to fit, although I've yet to try it:
