This is looking pricey. Is it true that the qts has it's own unique exhaust? I see systems for the 1.8 which are a decent price but all the qts systems seem to be £500 plus
No just back box as the v6 has 2x down pipes it can be made to fit have a look at byzan build thread as he has modded a S4 system to fit his TQS. If the whole thing needs doing id look at getting a custom system made and fitted and then you could go 2.75" or 3" or fork out on a milltek exhaust !!
Fitted a new clamp and it's still going strong although there is a slight blow from the flexi at the front. I'll either weld it or get a custom job made up when the time comes
