The downpipe from ecotune is to replace DPF AND downpipe all the way from turbo to the middlepipe og the exhaust.
Thats actually why I want it since the DPF acts as stuffing in the exhaust not letting the air pass easy.
According to Promotec i South Africa a possible gain of 30hp on my car is possible by removing the DPF and map it accordingly.
