His4 · 03-26-2019, 02:31 PM

Hi everyone, i run Stage 2 with catless downpipes.

my question is: do somebody know, how much power reduce the 400 cell gutted OEM downpipes compared to catless downpipes ?

i'm worry to lose 30-50 HP, if i remove the catless and install 400 cell DP :-(

thanks for help !!!

Do the oem cats have 2 monoliths in them? I'd be interested in removing one if it increased noise. Typical sports cats are 200 cell.

I have read that the standard cats are good up to 850hp, depending on the tune you would lose very little power running cats.
