JM Fabrication 3" Downpipes (R35 GT-R)

  • $ 77537

3" (76mm) Downpipes

The JMF R35 GTR downpipes are some of the highest flowing downpipes on the market with minimal restrictions. They are made from 3" diameter, 1- piece CNC mandrel bent 304 stainless steel tubing unlike many of our competitors who piece together several different bends creating extra welds. All of the flanges are CNC machined from 1/2" 304 stainless steel. HP gains expected can be anywhere from 50-100hp depending upon your setup.?? The downpipes will increase exhaust sound noticeably since the catalytic converters are no longer present.
