I went from stock system to 3" turbo back- I couldn't really feel much difference although it seemed to boost that bit stronger.
Then I went from full 3" turbo back to 3" down pipe & oem cat back..... From the above set up to this I can't say I've felt a significant Peformance drop
Obviously this is without mapping....... With mapping to suit a 3" turbo back would make more peak power than a 3" downpipe & oem cat back!!
I just hated how loud it was with a full 3" system.
I've had a 3" turbo back on my old Gsi and turbo type r (ep3) both weren't as loud as the 3" on my cupra lol
