I've noticed today that my headers were like 2.5L headers as shown in the picture, without any precat system. Is that a normal configuration ? I don't believe it is ? Could this be an issue or shall I see this as an upgrade as I have less flow restriction ? Could this be problematic to have 2.5L headers on a bigger engine, no restriction due to maybe smaller pipes ? Thanks. Michael.
