Primary or secondary cat-back for the Nissan GT-R R35?
The R35 runs two sets of catalysts, and Milltek offers a cat-back from each. The secondary cat-back starts behind the secondary cats, so every catalyst stays in place, which makes it the choice for a road car. The primary cat-back starts further forward, behind the primary cats, so it replaces the secondary cat section and is the louder, motorsport-oriented option.
Both are non-resonated, as is every Milltek Nissan system, and finish in GT-127 tips in polished, titanium or brushed titanium depending on the listing; see our tip styles page.
GT-R catalyst replacement pipes and secondary bypass
Closer to the turbos, the primary catalyst replacement pipes and the secondary catalyst bypass both remove catalysts. They are for off-road and competition use only, will fail an MOT emissions test and need an ECU remap. Compare them with other parts in our manifolds, de-cats and sports cats range.
Milltek cat-back for the Nissan 350Z 3.5 V6
The 350Z has one system: a cat-back for every 3.5 V6 car from 2003 to 2010. It bolts on behind the factory catalysts, so the emissions equipment is untouched and it suits a road-driven Z.
