Looking for anyone who has a bit of advice here as I'm struggling to find any information.
I currently own a standard Mk7 GTI, call my childish but I really want it to have a small amount of overrun and from what I can gather from various videos, the Clubsport S in its standard format sounds absolutely perfect! I've only done a res delete so far however I'm about to pull the trigger on the CSS backbox whilst I still can.
What I'm wondering is are there and differences between the downpipes in the CSS compared to the standard GTIs? AwesomeGTI advised that hardware-wise they were the same and the overrun run was software-related. If that's the case then why do so many tuners advise against overrun / crackle maps on stock downpipes? Is it in any way possible to run a mild crackle map on a standard GTI?
Any and all advice appreciated.
