Full 2 1/2" exhaust system designed and fabricated by me, with recycled pipes. Very minor surface rust, so after painting with High temp, should last many years after being coated on the inside with oily diesel soot. After the turbo install, this can easily be adapted. Also, this design can be copied at a later date. Still have a heat shield for the muffler, but later. Exhaust system sits higher than Transmission cross member, so will be great for me for a good while.
