Description
MANIFOLD-HEADERS
- CNC machined head flanges, heavy duty 7 to 12 mm thick steel, heat distortion resistent.
- Stainless steel tubes (for Cat. equipped models), or chrome plated, heavy duty steel tubes, 1,5 mm wall thickness, mandrel bent with CNC bending machines.
- Head tubes perfectly mated to the engine exhaust ports for smooth gas flow. Length and diameter are tuned to engine displacement and powerband characteristics.
- Joints between tubes are hand welded.
- Slide-on type connections are machined to perfect tolerances for leak proof fitting.
- An oxygen sensor is retained, where present in the OEM exhaust (no modification is needed to the engine management system).
Supersprint tubular headers are one of the must-have performance items for the M113 engine. These equal length, stainless steel headers replace the stock manifolds for an instant power and sound upgrade. This header kit opens up the exhaust for a less restrictive flow. Expect gains of at least 12hp with these and more if you have other modifications to the cams and intake. There is a beautiful sound to go with the torque and horsepower improvements.
