Muffler gas backpressure?
I've just installed a set of Pea-shooters from Epco and had the header's ceramic coated.a month ago.
I'm experiencing .. low torque starting out and mid-range.
Once it's going ..it's like a jet.
Do I need to jet up or down? I need to get more air to the air box
What is the best way to do this. I'm hoping to have this figured on on
