It's all to do with the shap that effects the power band.

Jp-1 more bottom end power

Jp-2 more bottom end to mid power

Jp-3 more mid to high end power

Jp-4 is more genaral power all round the rev range. ( if I remember correctly)

You can choice a pipe to suit you and your engine. When I run my rb ws7 3 I went for a jp-1 for more low down power as the Engine was a proper revy screamer, but each to there own

Yeah

jp1 is for bottom end power

Jp2 is top end

Jp3 is a mixture of both jp1 and 2

Jp4 is a revised version of the jp3 and is race legal better suited to racers
