How does back pressure effect your exhaust and performance?

One last question that has nothing to do with back pressure...How can i shrink my pictures down enough to 100x100, to fit my avatar?
you've gotta use photo editor, photoshop, or some picture editing program.

Losing backpressure is good, losing ALL backpressure is bad. Too long to explain . . .

this is actually a pretty good explanation.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
