Synapse Engineering's competition-proven mid-pipe for the R35 GTR. This configuration is made of 304 Stainless Steel. This configuration has been designed and tested in competition. Although heavier than Titanium, 304SS has 2x the shear strength of Titanium under normal and extreme operating temperatures. This is the race configuration that elevates the exhaust note and does not include resonators or catalytic converters.

If this will be your only upgrade to your R35 GTR, or in conjunction with a cat-back exhaust system, we recommend the elimination of the catalytic converters for optimum horsepower gains. If this upgrade will be in conjunction with the Synapse downpipes, you can add the catalysts to the mid-pipe, and not the downpipes, if you elect to do so on your race car.
