How exactly does backpressure work? The only thing I can imagine it being is some way of the exhaust gases "pushing" off of the air currently in the exhaust tubing to create a bit of resistance in some way. Completely wrong?
I know that you can't just take off everything on your exhaust system including the muffler and expect it to run great, but how come a high flow muffler is that much better than stock? Wouldn't it need to be more restrictive to get the necessary backpressure?
When does the system start to lack the necessary pressure... after both resonators are off, cat if off, or both?
Questions I've always wondered .....
