Collar/manifold Special , NSR250

This is a special replacement part for the NSR250. The manifold has a CNC machined profile, matching the exhaust port exit to allow smooth exhaust gas transition from the cylinder into the expansion chamber. This helps to increase performance from as little as 7,000rpm all the way up to and beyond peak power.

Stephen A’lee of George White Superbikes in the UK independently dyno tested the manifolds on a stock engine MC21, with Stock airbox. The only mods were TYGA pipes.

The red trace shows the above bike using the supplied EXMN-0003 manifold with a peak of 57.2hp.

The blue trace shows the same bike with EXMN-9003 special manifolds fitted. A gain of 1.4hp with no jetting changes.

Compatible with the following TYGA system:

EXCS-0003

EXCS-0005

EXCS-0006
