The suitcase deletes that we sell are enformed in our unit to fit over the size of the standard system.
If you are experiencing any problems with fitting this system then give us a call and request to speak with Chris who designed both our MK5 Golf GTI TBE system and this style of suitcase delete.
We have not heard of any problems concerning this product but would be more than happy to assist in whatever way we can
Is the blue flame pipe work not a larger diameter?
Both our TBE and Suitcase Delete Systems are a larger than standard diameter. However, our TBE system is a larger diameter than our Suitcase Delete.
