Terrible sound after pre-cat removal

Recommended Posts

Will post sound tomorrow with video, I mean so it just because nothing blocks gases now, so it is expanding in tube and doing bang, If anyone have stainless flexible decat pipe fitted and have good sound it will be good to know, ecu is still untoched, so it might be fuel as well. But on higher rpm sounds good. Up pipe is still sane, I just pulled cat out

all cats was removed, it was huge downpipe and rest of exhaust fitted, that noise started after pulling pre cat out of pipe, but pipe itself was not swapped.


I'm not soure if decat up pipe is worth of trying, but if nothing else, there's that metal hose at the middle, later today I will post video
