Suzuki Swift 1.4 Exhaust Header R&D

We have conducted an R&D with two header designs on the 3rd generation auto transmission Suzuki Swift 1.4L (ZC82S), namely the 4-2-1 and 4-1 exhaust header, to see if they do any good with this 1.4L K14B inline 4-cylinder engine.

We produced both the exhaust headers with grade 304 stainless steel CNC mandrel bent pipings and full TIG/Argon welded.

Comparing the factory stock standard Suzuki Swift 1.4L exhaust header, the stainless steel 4-2-1 and the 4-1 header (LEFT TO RIGHT). Note the right most header is turned 

We brought all three exhaust headers onto the dyno machine and here is the results.

The horse power and torque improved. Based on the air-fuel ratio graph, there are plenty of rooms for further ecu tuning or remapping if more horse power is desired.
