Outer Limits 4x4 Board

as above who has made there own dump pipe and if out what material and any pics

I made one for my 80series.
I used some mild steel exhaust mandrel bends from a truck supplies place.
I cut a flange out of 12mm steel, cut and shaped the end of the 4" mandrel bend to fit into the flange.
Cut two mandrel bends to approx75deg to get past firewall and under the floor, I ran my exhaust between chassis rail and the gearbox in 4" tapered it to 3" at the transfer case, fitted a 14"long braided flex then 3" mandrel bends and pipe to the rear with a straight through 3" muffler at the rear. No bend is over 45 dgrees after the dump pipe.



photo was taken in the dark so its not the best

Heres mine

I did basically the same as Zoltan, though I cut the ends off the bends to make two 75degree bends rather than two 90degree bends to try and ease gas flow as much as possible
