Best Turboback?

Exhaust tubing provides back pressure effecting the engines tq output. A dyno sheet link might be nice, I couldn't find one

and the bold part is a reference to NA engines. Read up.
I can show the Dyno sheets of my own that include a baseline , then a Turboback 3" exhaust or you can read for yourself in David Buschurs massive dyno thread where he tests his 3' system vs his 2.5' system. I don't think you searched hard enough because this has been discussed before .

Do I smell TTBE?
