Bygger nok opp en del mer varme og rundt turbo og med dette egt systemet sender den bare enda mer varme tilbake til motor, å når det chippes så kan det komme mer svart røyk som inneholder mer sot og dette tetter cat og DPF raskere så er bra og være obs på dette,
sitat med noen som har over 20 års efaring med bmw deiesel maskiner.. ordne eksosen er ett must for de som drar ut nesten 300hk og 600NM+++ av en 530d
Performance - You will enjoy reduced turbo lag and quite a remarkable performance difference throughout the entire rev range, the original downpipe has a near 90 degree angle into a restrictive "heat soaked" cat which is replaced with a smooth bend and unnecessary under bonnet heat is reduced. The retrictive DPF which is prone to clogging and premature failure is removed in favour of a straight through pipe further improving flow and reducing power robbing back pressure.
Economy - If your DPF has failed then you will experience a substantial fuel economy improvement. On a healthy vehicle mpg gains in the region of 5-7mpg are consistantly reported.
Longevity - Your upgraded exhaust components are over-engineered in 316 Marine Grade stainless steel and the flexible coupling in 304 Grade stainless steel, your new parts should outlast the life of your vehicle.
