Custom made exhaust with particulate filter delete
We have begun to fabricate our custom made exhaust system with OPF delete. As we intent to make a sportier, but not loud sound than the factory one including OPF, we:
- use one exhaust pipe until the end-muffler - and put two pass-through resonator (bigger one and smaller one) to sort out some noise - will use of course exhaust valves and a well design end-muffler with - carbon tail pipes. More picture and sound file comes next days. As for the software regarding OPFless, i have two solutions in my mind: - install BM3 OEM CS software, which does not look for OPF - use the factory software with MR's solution which somehow fools the ECU (but has a side affect, as the ECU still wants to regenerate the non existen OPF. As far as I know ECU leans the air-fuel mixture to generate more heat and burn out the passive OPF.) Best regards, Laszlo |
