from what i heard...or rather what i was told is that backpressure can be a good thing and that engines do need a certain bit to perform optimally. Now dont quote me on this and i could be wrong...but going with larger exhaust on bigger v8 v6 engines is fine, or turboed supercharged engines, but on engines like ours, i think losing backpressure can actually be not good, therefore backpressure can be a good thing?
