CSP 1.5 inch python exhaust collector cone insert. Supplied each

The performance characteristic of the engine can be affected by the use of a collector cone insert in addition with the python exhaust system. The large 2 1/2 inch flange diameter can be reduced down by 1-1 1/2 inch by using one of these cone inserts. As a result the higher gas acceleration can affect the lower RMP range. As a result it is possible that you feel a noticeable torque increase in lower and middle RPM ranges, which is more preferred for daily driving.
