i was wondering what could/would happen when i put my full jardine gp1 exhaust system on if i dont rejet. i plan on rejetting to stage 3 jets in a couple weeks after i get the exhaust on just wanted to make sure it wouldnt hurt it
You won't hurt it over a short time I'd say. What's the matter? Getting anxious are we? The problem with free flowing exhaust and not retuning the fuel delivery system is creating a lean environment, which over time can burn up valves and cause some major issues.
