ok,
reading some other forums, people seem to have their facts confused. backpressure this and that.

especially concerning turbocharged setups. someone will say they ran their stock exhaust with a turbo setup, then took it off and low alot of low end. i dunno if they have a screwy butt dyno, but something just sounds wrong with that phrase.

can someone please explain the odds and ends of backpressure on turbo setups (i do realize they create their own backpressure) and i want to help them, but even my facts arent straight. does their exhaust diameter really kill their low end? i know bigger piping allows more flow.

id type more but its hard to explain. someone throw up some good stuff.
