manifold, which attaches to the tuned pipe using three small springs
and a manifold gasket (included). This pipe is designed for all around
performance, specifically with the Ninja JX21 B01 engine.

purchased separately. This pipe is made available as a separate item so

you want better top or bottom end performance.
