V8 Diesel Exhausts

Hey guys... concidering a V8 diesel conversion from a 5.0L petrol. I currently have extractors with an isolated twin system with only one big muffler on each side. The pipes are quite short and dump just before the drivers side back wheel (australian)

If and when i put the diesel in, can i just use new diesel extractors to the existing pipes, or do diesels require anything extra.

I am aware that it wont be legal, but will it work?

Re: V8 Diesel Exhausts

Diesels do require more (bigger) exhaust. Look at trucks with diesel and gasoline motors...the diesel ones always have bigger pipes. As far as converting, I've never heard of anyone doing that. There's just so much difference between the 2 types of motors. Like I said, I am ignorant if anybody has done this, but just looks like a lot of trouble. Conversely, diesels will require greater air intake. They also use much higher compression. They don't have spark plugs...I wouldn't know where to start...

Re: V8 Diesel Exhausts

with non turbo diesel u have to have at least one muffler and the pipe should be no bigger than 2.5" and with turbo diesel up to 3.5" is okay (depends on size of engine) and require no muffler as the turbo does its job, but check with your states laws. Also a "flex" should be put in between the extrators and the pipe otherwise the diesel engine will shake it apart. Any questions, just pm me and i ask my mates (were all 4x4 mad - and most of us like diesels)
