From VSR:
''The only aftermarket center section with dual high-flow catalytic converters on the market! Mandrel bent Stainless Steel tubing fully welded and designed to fit with either a stock muffler or most any aftermarket muffler. This system weighs less, flows better, meets emission standards and has the crossovers that the S14 engine needs for power and efficiency.

Dyno testing has shown a gain of 4-5 hp over the stock catalytic converters, but more importantly a significant gain in torque at lower rpms.

We designed it to tuck up high in the transmission tunnel for more clearance and less aerodynamic drag and eliminated many of the unnecessary bends and the power robbing crushed section under the rear suspension. All for a price close to half the factory replacement section!"
