Cat back deffo made difference. cant quantify but if you look on MRC FB page you can clearly see the power increase with even just a cat back.

Car manufacturers always work to a budget, so if they can get the desired power / effect with a smaller pipe for example and save some money they will. No point having a 3" pipe that can flow over 1000bhp if you only need 560bhp and a 2.5 (or what ever) will suffice.
True - what suits standard output is likely very different from what you are aiming for. Keep us posted.
I will. I got delayed messing with my car ramp, small job tuned into a nightmare!!. Got there now though. Front pipes will be on this time home then some map tweaking and see how it goes.
BMW 540i
2018 GTR
F90 M5
X3MC
RS3 Saloon
RS7 FL best car I've owned. No faith in turbo oil screen (turbos failing) or sticking oil scraper ring causing missfires.
F10 M5 LCI still no rear grip lol
S7 black Edition Too big and heavy
S3 8V FL DSG 310ps, road noise is a joke
RS3 8P Rubbish
C7 RS6 Fantastic car but missed playing
GTR R35 800bhp, too extreme, crazy fast though
911 Turbo Remapped. Hated it
F10 M5, awesome but no rear grip
RS6 V10 700BHP crazy
Porsche Cayenne Turbo S 600bhp
