Overview

The PPE Engineering 837001-PM-SS is a set of long tube race headers designed for maximum power gains. Constructed from T304 stainless steel with equal-length, 16-gauge tubing, these headers feature 3/8" thick laser-cut flanges and a parallel merge collector. They are 100% TIG welded and include porting at the flanges and flat-sanded head flanges.

Show original supplier description

The PPE Engineering 837001-PM-SS race headers are engineered for maximum power output, specifically designed for Nissan 370Z, Infiniti G37, and Q50 models from 2009 onwards. These headers feature equal-length, 16-gauge tubing constructed from durable T304 stainless steel, ensuring longevity and performance. The construction includes 100% TIG welding, 3/8" thick laser-cut flanges, and a parallel merge collector designed to optimize exhaust flow. Installation involves replacing the stock catalytic converters, making these headers intended for off-road use only. Testing on a stock 2010 370Z Nismo demonstrated an increase of 23 wheel horsepower (whp), with even greater gains of up to 35 whp possible when combined with a tune, such as UPREV. These headers are compatible with both RWD and AWD configurations. The PPE Engineering 837001-PM-SS headers come with a 1-year warranty. Optional ceramic coatings are available for enhanced durability and aesthetics. For applications requiring catalytic converters within 6 inches of the stock location, an optional Y-pipe with integrated high-flow cats and a 3-inch outlet is offered.
