i'm going to sort out exhaust on my 2.0 HDi xsara, and i want to know what you guys think i should do.
i though replacing cat with a de-cat pipe and installing a backbox (full flow, ofcourse).
i intend to remap ECU before summer, so bare that in mind.
do you think i should remove the midbox aswell? or simply replace the entire pipe down to backbox?
I'M GOING TO DO THAT TOMORROW, SO PLEASE HELP
