You guys make it seem like the VG engine needs backpressure. I don't know if I agree with you on that, but I plan on making my exhaust piping 2.5" from the headers to mufflers to a 3" (or 4") single outlet (cats removed). With an intake and pulley, I'm guessing that I'll hopefully get 300 hp at the crank.
What I'm more curious to know is what some of you predict will happen if I go with this exhaust setup.
