  3. Cupra 300 st with mk7.5 golf estate exhaust

    Hey guys recently fitted 2 rear boxes from a 7.5 R estate, ive studied this thread long and hard and possibly later today will be cutting them open to view internals and see if a more direct un-baffled route can be made. After watching and reading previous owners fitting the same exhaust i...
  4. CUPRA ST 300 BACKBOX DELETE

    Very informative thank you!! I have option 3 I got a mid section back from a gpf 7.5 estate so basically I just need to butcher the boxes open and investigate and see what I can do I would go for an expensive system for obvious reasons however none I've seen really seem any different to my...
  5. CUPRA ST 300 BACKBOX DELETE

    Well spotted!! But it still internally is more straight through rather than redirected through baffles presumably because there is a center silencer on the 7 estate I wonder if my 7.5 rear boxes revert back to the cupra style due to being the only silencers in the system only one way to find out...

  12. CUPRA ST 300 BACKBOX DELETE

    ahh sorry well both systems (standard and golf r) didn't have centre res as both are from gpf equipped cars, a lot of my sound suppression comes from the twin gpfs i think so i didn't know if deleting both rear boxes would be much louder just to hear farts etc. cheers
